Well, finally got a chance to clear out the butterfly habitats, inspecting every leaf, fresh or otherwise, and also dumping out the frass on the bottom.
Counted 15 Monarchs--3 chrysalises, 1 in J position, and 11 big strapping looking cats who look like they should be heading up to the top soon to pupate, instead of lounging around on the milkweed! See what I mean??
Counted 11 BST cats, including 1 chrysalis. 4 are very small early instars--at least a couple of the tiny ones are visible in the photo. Most of the others look like they should be building their slings within the next week... So it's like I have a set of bigger BST cats, and a smaller group of very early instars...
well, they do provide me with endless entertainment!!
