For the last few years, our family has really enjoyed watching the monarch life cycle at the house. By this point in the season, our milkweed plants are usually wiped out two or three times by batches of caterpillars. Our two little girls get a kick out of counting the caterpillars then seeing where they set up their chrysalis around our porch.

This year has been a completely different story. We’ve seen a few monarch butterflies here and there, but haven’t found a single caterpillar. Located n the South Baton Rouge area, and our milkweed plants are as thick and healthy as ever.

Has anyone else noticed a similar drop-off this year?

those are probably giant swallowtail. If you want to get rid of them pluck them off and put them in a box I’ll take them

They got my one little 2 week old dill plant. Ate it down to where it was only stalks. Pulled 5 fat caterpillars off

How the hell did they find that random dill plant?!?!

Fed them to the chickens because I was mad at them. Next time I’ll keep a few and watch the show.

Monarchs do not lay eggs on or eat anything except milkweed. That's why their population is endangered. Milkweed habitats are running low.

yes…the caterpillars on dill are black swallowtail and the ones on citrus are giant swallowtail, both very common and not endangered

In Prairieville and we've had a few butterflies (less than usual), but we have a lot of caterpillars right now.

Not at my house, they are everywhere, I have native milkweed and tropical, I have been cutting of seed pods, I have one bed, covered in milkweed with some Zinnias mixed in . I'm sure a lot of these Monarchs are natives and don't migrate but I have a lot of butterflies

Seen a couple of females laying eggs on my milkweed, seen a chrysalis or 2 and a few mid sized cats wandering around. But no where the usual activity. Once I see that I have cats on a plant I will cover it with fine mesh to keep the damn red wasps away they hunt the young caterpillars

You’re right. I have milkweed planted and still have all my leaves.

Go to one of the local big box stores selling milkweed...buy a plant that you see eggs or caterpillars on and bring it home. That one plant won't be enough for them anyway.

Call it a rehoming deal...for the price of one milkweed plant.

Just an update. We have been getting egg bombed routinely. I've got 60 caterpillars right now who have eaten almost all of the milkweed we've got. We're brought in a few more plants and moved some to larger, less desirable apparently milkweed. Hopefully they'll turn into chrysalises soon.
