There are between 40 and 50 caterpillars in one of my aquariums. They are eating me out of house and home lol. I put 5 of these gigantic leaves in there last night before I went to bed and they were gone this morning. Put 5 more in this morning and they are almost gone.
It's hard to believe that something this small can have such a big appetite but I have seen entire trees stripped of their foliage but caterpillars so it shouldn't surprise me. Good shot of your fellas.
Wow! I know they're voracious! Not these but other caterpillars ate all the leaves off the azaleas this spring. I have over 50 bushes and they were down to the nubs!
@tesssa They are milkweed leaves. That is the only thing that Monarch caterpillars can eat.
