Hi, I started growing milkweed 3 or 4 years ago and have dealt with orange aphids, tussock moths, but alas no Monarchs (yet??) When I saw the larvae/caterpillars on this leaf this AM I thought, eradicate, must eradicate (I was squishing orange aphids at the time). I stopped myself, hopeful, maybe, just maybe these are Monarchs. Well, none of the popular "web images" of monarchs look like this -- and nor do Tussock Moth images. One TM image did seem to have these black-headed crawlers amongst the fuzzy tufted TMs, But I can't be sure. Thought maybe they could be leaf-miners, so far no damage though. So, anybody, are these very very young TM larvae or, dare I hope, Monarchs or .... thanks. If they are TM larvae should I 100% eradicate? or let a small percentage continue?
