Wildflower Plantings

I didn't get a chance to visit the health club today, so I took my 2-mile walk up the road instead. Along the way I noticed there was some Stiff Goldenrod growing in the roadside ditch. I've been wanting to get some of this for my backyard for quite a while -- the flowers are an excellent source of nectar and very attractive to butterflies and bees. I dug up at least 8 plants from the ditch. I also dug up some sunflowers -- Woodland Sunflowers, I think. My plan was to put all of these plants out in that wild, unmowed acre of my backyard.

I also found and dug up several of these interesting looking plants. The seed pod on them led me to believe they were some sort of milkweed. When I cracked open one of the seed pods, they definitely looked like milkweed seeds inside. What do you think?
After I got everything planted and came back in to my computer, I went to the MonarchWatch website because they have photos of all the different varieties of milkweeds. To me this plant looked exactly like Plains Milkweed, which supposedly is not found in Minnesota. OK, now I was really curious, so I googled "Plains Milkweed" and here's what I found on the USDA Plants Database website for Plains Milkweed. Check out the range map on this website -- it also shows this plant is not found in Minnesota! I got all 4 plants in the ground and marked so I'll be able to check and see if they make it through the winter. I hope they do because I want to see if it grows and spreads on its own and how attractive it will be for the monarch caterpillars and other butterflies and insects next spring.

Most of the wildflowers I've planted previously in this wild acre haven't survived (the soil is really crappy), but I was happy to see that this plant and another just like it had survived and were thriving. It's one of the hyssops and the leaves have a wonderful sweet minty-licorice scent when you rub them between your fingers.

While I walking through the tall grass searching for spots to plant my new wildflowers, I noticed there were lots of spider webs created and populated by these beautiful Banded Garden Spiders.
The webs were hard to spot in the bright afternoon sunshine and I hope I didn't accidentally destroy any of them.

It was a beautiful afternoon to be outdoors, a light breeze, and about 65 degrees. The only negative thing was the swarms of hungry mosquitoes just waiting for me to walk through the tall grass. Where are those dragonflies when you need them?

Hope you're not tired of monarchs yet!

I pulled a few weeds in the garden yesterday afternoon and threw them into the wheelbarrow for Mr. Johnson to dispose of . After dumping the weeds, he came into the house and asked me whether I had noticed the monarch chrysalis on the wheelbarrow. Sadly, I hadn't noticed it at all.

The wheelbarrow always sits in the same spot in the backyard next to the compost box. On top of the compost box in a long flower box, I'm growing some more milkweed plants (sometimes known as butterfly weed [Asclepia tuberosa]) from seed. These little seedlings are only a few inches tall, but they're very attractive to the monarch caterpillars. I bet the chrysalis on this wheelbarrow is from one of those caterpillars that was snacking on those butterfly weed seedlings earlier this week.
After taking this photograph, I removed the chrysalis from the wheelbarrow and placed it in monarch ranch along with the 17 other chrysalis still waiting to hatch into monarch butterflies.

Another milkweed plant in my yard that's receiving lots of attention from monarch caterpillars this summer is this Swamp White Milkweed. I planted it last summer and was happy to see that it made it through the winter and has developed into a huge, beautiful plant this summer. It has been blooming for several weeks now and has even developed some seed pods that I will save and try to grow more plants from next spring.

I'm amazed at how much the monarch caterpillars love this plant! It's not unusual for me to find at least 5-6 caterpillars on it every day. I collected 5 for the monarch ranch earlier this afternoon and then found these 2 additional ones a couple hours later.

I think there are at least 16 caterpillars of all sizes crawling around in the monarch ranch right now. At this rate, I shouldn't have any problem achieving my goal of raising, tagging and releasing 50 monarch butterflies in my backyard this summer.

Let's Talk About Monarch Caterpillars

My next couple of posts are going to be devoted solely to talking about monarchs, so hopefully these will answer any questions you might have in case you're thinking about raising monarchs for yourself.

By now, you've probably heard or read the news that the monarch numbers (and butterflies in general) are all down this summer--perhaps due to the chillier and wetter than usual weather many of us have been experiencing this summer.

I've been finding quite a few monarch caterpillars in the backyard this week and here's a look at my re-populated monarch ranch.

Here are 4 large caterpillars I found on 2 plants the other night.
Monarch ranching is a really fun project that you might want to pursue with your kids or grandkids (or even on your own as I do!). So let's say you want to start a ranch, let me share some tips with you for going out and finding some caterpillars yourself.

First of all, you've got to find some Common Milkweed--the caterpillar's favorite food source. Hopefully you'll have some of this growing in your backyard or somewhere nearby. (And of course, you don't want to pick any that's been sprayed with chemicals.) The best thing to look for is a leaf that's been munched on. If you're lucky, the caterpillar will still be there and if you're really lucky, the caterpillar will be on top of the leaf!

Another clue to look for is poop (frass) on the leaves below where a caterpillar might be. The bigger the frass, the bigger the caterpillar you'll find.

Here's a lucky find--3 caterpillars on one plant, but notice that 2 are hiding underneath the leaves.

If you do find some caterpillars to populate your ranch, remember that you'll have to continue feeding them. I usually pick several leaves while I'm out there and store them in a baggie in the fridge. Once the caterpillars get bigger, they're eating machines, so you have to make sure you've got enough food to keep them fed until they turn into a chrysalis.

And speaking of chrysalis, take a look at what I also found yesterday........
A monarch chrysalis in the wild!! In all of my 50 years on this earth, it's the first time I've ever seen one! I was trimming back this huge milkweed patch next to the driveway because it had gotten too overgrown and was obstructing our view when backing out. The breeze just happened to blow this leaf back and I spotted the chrysalis. Thank goodness I didn't cut this stalk off before I saw the chrysalis.

Here's what it looked like when the leaf was just hanging--what amazing camouflage!

So I decided to remove this chrysalis from the leaf and add it to my ranch to see if it would hatch. Did you know you could do that? Let me show you how I did it. And before I go any further, I should tell you that I learned this from Dave, my monarch monitoring/bluebirding/master naturalist mentor.

Because this leaf would die before the butterfly hatched and the chrysalis has to hang in order for the butterfly to develop properly, I had to get it off the leaf.

See that little black "stem" at the top of the chrysalis? It's very stiff and hard, so this is what I'm going to attach a hanging thread to. That will allow me to tie the chrysalis to the roof of my monarch ranch. I put a needle at each end of the thread to make it easier to work with and just tied a good, tight square knot around the black stem.

Before the caterpillar turns into the chrysalis, it attaches itself to the underside of where the chrysalis will hang with a strong patch of silk. My next step was to carefully remove this silk patch from the leaf, so I pulled the handy-dandy Leatherman Micra from my pocket (you carry one of these with you at all times, right?) and gently loosened the silk patch from the leaf.

Once it's loosened, the entire patch was easily removed from the leaf.

Ta-Da!!! A monarch chrysalis ready to be attached to the ceiling of my monarch ranch.

In previous years, I've collected mostly eggs and raised them into caterpillars. This is the first year when the majority of my monarch butterflies will be hatched from larger caterpillars found in the backyard. There is a little bit more risk in hatching monarchs this way, mainly due to the chance of parasitic wasps or flies laying their eggs in the larva. There is no visible evidence when this occurs, but usually what happens is the butterfly is unable to develop due to the parasitic wasp or fly which develops instead inside the chrysalis. I've only had it happen a couple of times, but it's quite disappointing and something that you want to be aware of in case it happens in your monarch ranch.

Before I finish, here is an excellent website (just click on the link) if you're looking for more information on monarchs: Monarch Watch. I also really like "The Butterfly Book" by Don & Lillian Stokes as a reference guide. And I would be more than happy to try and answer any questions you have also. You can leave a comment or feel free to e-mail me (rjknits at msn dot com).

I hope you enjoyed learning more about collecting monarch caterpillars. Next time, I'm going to show you how to tag the monarch butterflies that you've raised in your ranch.

Summer Volunteer Project

To retain my Master Naturalist certification, I'm required to complete a minimum of 40 volunteer service hours. The Monarch Larva Monitoring Project is one of the ways I've been obtaining my volunteer hours. Every Wednesday evening, a small number of dedicated volunteers head over to the Payne Field near Rochester's Quarry Hill Nature Center to look for monarch eggs and caterpillars. In the photo below, my buddy Dave begins his search. Dave is also a fellow Master Naturalist volunteer and bluebird enthusiast. We met years ago when he first moved to Rochester and I was working at Wild Birds Unlimited. It's been fun spending time with him again on volunteer projects at Quarry Hill and Master Naturalist events.

Here's Lucille and her two children on the monarch quest. They ride over on their bikes every week, but Lucille admitted to me last week that she's enjoying this project much more than the kids are.

Every week, we fill out a checklist indicating what we find in the field. We tally each plant that's inspected and if eggs or caterpillars are found, that's also tallied. The caterpillars are also categorized by size: 1st, 2nd, 3rd, 4th, or 5th instar. Here on my clipboard is a lovely 5th instar I found during the monitoring. (This caterpillar went home with me, turned into a chrysalis the next day and I'm now waiting for it to emerge as a monarch butterfly.)

The first few weeks of monitoring in June were great -- the milkweed plants were taller than the surrounding grass and it was easy to get through the field. Now look at it! Some of the grasses and weeds are almost up to my chin! I have to be pretty careful bending over to inspect the milkweed plants lest I get poked in the eye or ear by some foxtails or wild parsnip.

As I've mentioned before, the low numbers of monarch eggs, larva and even butterflies has been disappointing. But there are plenty of other insect sightings in this field to keep things interesting. Lately I've been seeing lots of milkweed beetles doin' the "wild thing," but this is the only time I've ever seen this particular position........and I just couldn't resist taking a picture!
Looks pretty precarious to me, but I guess even beetles like a little variety!


I'm happy to report that my monarch butterfly tagging kit finally arrived in today's mail. My monarch ranch has at least one butterfly scheduled to emerge from its chrysalis early next week, and I hope to share a "how to tag a monarch butterfly" post with you then, so stay tuned!

Random Friday

Happy 3rd of July! I hope some of you are enjoying this day as a holiday from work (I sure am!) It's been a while since my last post, so here's a potpourri of observations from the past week.

A look in the garden the other day revealed that some thing were missing--like beet tops.......


and pea sprouts!

Since I'm reasonably certain Peter Cottontail and his buddies can't access the garden, my immediate suspect was Bambi's mom and sure enough, after very little searching, I found her hoofprint (several, actually!)
Obviously the greens provided a tasty diversion from the usual nightly feast of corn and birdseed and my 3-foot fence was no obstacle for Mrs. White-Tail. Liquid Fence to the rescue! I mixed up a fresh batch of this horrible-smelling stuff and applied a liberal dose to all of this tempting salad bar. And it worked! Here's some of the beautiful fresh lettuce and peas I used to make us delicious salads for supper last night. (those peas were so sweet--no wonder the deer liked them!)

There are lots of flowers blooming all over the place right now. Here are some of the sweet-smelling blossoms on the staghorn sumac bushes. This busy little bumblebee was loving it! See all the pollen collected on his/her back legs?

I'm starting to see some butterflies, but the butterfly activity seems slow this summer. I think this is a Pearl Crescent.

The common milkweed in my yard is starting to bloom. I actually saw a couple of monarchs checking out the flowers for nectar. The monarch numbers seem to be down this year too and I have yet to find any eggs or larvae on any of my milkweed plants.
Hopefully there's just a delay in their migration and things will pick up soon--I've got a brand new monarch ranch on the kitchen counter just waiting to be populated with caterpillars.

Two of my neighbors have beehives now and I'm guessing this might be one of their honeybees checking out the milkweed blossoms for nectar too.

Did you get your new "license to bird" yet?
The new duck stamps are available at your local post office and you don't have to be a duck hunter. "Federal Duck Stamp Dollars are used to purchase wetlands and other valuable habitat for the National Wildlife Refuge System, benefitting many different birds and other wildlife species."

Another plus: your duck stamp can be used as a season pass to any National Wildlife Refuge! (where you might be able to see the really neat Long-Tailed Duck pictured on this stamp)

I saw this inside my compost bin the other day.......
Thanks to Susan's post a couple weeks ago about slime mold in her yard, I was pretty certain that's what this was. So instead of being grossed out, I was pretty excited!

Two of the baby chickadees have fledged and have been seen hanging around the yard.
A nest box check last evening revealed two little ones still inside. I don't know how those overworked parents can manage it, but they're looking pretty frazzled when they stop by to pick up some mealworms.

Thus ends another nerdy post from the Nature Knitter. Since you've read this to the end, you may be a nature nerd too--check out The Nature Lady's blog and take the quiz. (I believe I answered "yes" to 15 of the 16 questions.) It's time to come out of the closet and declare yourself as a Nature Nerd too! Finally it's cool to be a nerd! Woo-Hoo!


Have a great weekend everyone!

A Backyard Walk With Sophie

Finally we saw the sun for a few short hours this morning (first time since last Friday!) Here's where working part-time is great because Sophie and I got to take advantage of a nice morning and go for a little hike in the backyard. Come on along and I'll show you some of the things we saw.......

In spite of being almost 12 years old, a heart murmur and hind feet with no feeling in them, Sophie still loves to get out and run in the backyard. I don't take her for long walks anymore and she spent the rest of the afternoon napping after this adventure, but I think you can see how much she's enjoying being out here!

There's nothing wrong with Sophie's "sniffer" though. I bet she was smelling a bunneh under this tree.

When we were exploring at the farthest end of our yard, I noticed this fresh deposit of deer droppings.

Very close to where I found these droppings, we have an area of the yard that we've never mowed or done anything else with -- in fact, it's where we dump tree trimmings and other yard waste. It's grown up into a pretty dense thicket, but as you can see below, there's a little path going into this thicket......

and when I followed the path into there, I spotted this fresh deer hoofprint also.

Sophie was checking out all the good scents in there too, but I didn't let her snoop around too much because I wouldn't be the least bit surprised if a doe hasn't hidden a fawn or two in that area! Wouldn't that be a real treat to see someday? I'll definitely be keeping a closer watch on this part of the yard now.

I've got quite a few cavity-nesting birds occupying some space in the backyard also. There are three active Tree Swallow nests. This little female Tree Swallow was reluctant to vacate her house, but I wanted to see if her eggs had hatched yet.

Not yet! Just 6 pretty little white eggs in a lovely bed of feathers. I'm always amazed at the variety of feathers the Tree Swallows can find to line their nests. Does anyone know if that stripey feather right down in front is from a hawk? (click on the photo to enlarge it)

I also have Tree Swallows nesting in two of these plastic super gourds, but they place their nests against the back wall of the gourds, so it's impossible to see how many eggs there are and whether they've hatched or not. But I know the nests are still active because I see the swallows going in and out.

Mrs. Chickadee is still sitting on her 5 eggs in this front yard nest box. According to my incubation calculations, there should be baby chickadees hatching by this weekend and I'll keep you posted on any new developments.

I have bluebirds in a nestbox in the backyard too. There was an unsuccessful nesting attempt earlier in the season and I'm not sure what happened, but that nest had been abandoned. Now a new nest with 5 eggs is being tended by the bluebird pair. Another neat thing about this is that I've finally found a nest that incorporates some of the yarn scraps that I put out in the backyard every spring!

Here's a nice shot of Mrs. Bluebird waiting for me and Sophie to get the heck out of her territory!

A quick check on the vegetable garden revealed these broccoli sprouts from the seeds I planted a couple weeks ago.

The garbage can potatoes are doing pretty good too.


Remember the scenes of the wildflower garden that I burned on April 13th?


Here's what it's looking like today. No buds or blossoms yet, but everything has grown back very nicely. With all the rain that we've had recently, once it gets sunny and warms up again, these flowers are really going to take off.

The wild grape vine has really taken over the dead tree in my front yard. Right now it looks there's going to be a good crop of grapes later this summer and the dead tree isn't quite so unsightly now that it's covered with green leaves again.
The house sparrows finally took over the nesting cavity that I showed you in this tree earlier this spring. I wasn't real happy about that, but a windstorm a couple weeks ago blew the top part of the tree off right at that nesting cavity, so the sparrows lost their home anyway. (I'm so glad the bluebirds weren't nesting there when that happened!)

I've got a bumper crop of common milkweed growing next to my driveway this year. I have only seen 1 monarch butterfly in my yard so far this spring, but hopefully when they come back, they'll find this milkweed patch along with several others that are growing in different spots in the yard.


And finally, a couple weeks ago I cleaned out some dead plants and replanted some new perennials in my hummingbird and butterfly garden. One of my new plants is this Foxglove. It's the only one blooming so far, but isn't it pretty?

Thanks for coming along with Sophie and me on this walk.....we had a good time and hope you did too.
