Susan,

I've had that problem here also. I finally released all the caterpillars that had not eclosed to fend for themselves. They seem to be doing OK. However, the milkweed is getting bare, and they ate all the honeyvine already. I had cats eating chrysalides even with food available. I've never had this happen before. But, now I know Monarchs will eat the pupae. It wasn't a pretty sight.

Can you drive around and see if there is any common milkweed growing along the roads near you? You can cut stems and put them in a vase. Or how about posting on other forums you might be a member of? You never know, there may be someone that knows where some milkweed is near you. Finally, is there a botanical garden near you? Maybe they could help.

I am fortunate that there is a milkweed patch near me, so if I run out, I can go there and get some replenishment.

'Sorry that you're running out of MW, Susan!
If you actually see her laying more eggs, and you want to fool with packing up a few, like less than 10 eggs, I'll take them. I've only got one big tropical MW plant, plus a good bit of honeyvine, but it takes so much to fill up those monarch cats, as you well know. You'd need to mail them off immediately, since they hatch quickly, as I recall.
Maybe you can find some roadside MW, like weed30 said - that would sure help!

Lucky!!!! I have tons of milkweed, no Monarchs :-(
