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.
