The second photo shows a very bizarre katydid-like insect (Orthoptera: Tettigoniidae), with a rounded green cricket-like body, long antennae, and a strangely flattened head. It took me a while to figure out what I was looking at. The flat face is covered with light colored nodules and the jaws are black, giving the appearance of a crinkled, folded leaf with holes in it! Only when it moved did I see what it was. Apparently this species is carnivorous.

I also saw 2 tiny orange flea beetles with black legs sitting on Passiflora vitifolia. At first I thought it might be another species to add to my study, but after looking I couldn't find any sign that the beetles were feeding. I suspect they were just sitting on the plant. Later another large flea beetle landed near a P. auriculata, but it too showed no signs of feeding on Passiflora. So far, in all my work here at La Selva, I have consistently found the same set of flea beetles. The only exception is I haven't recently seen the "fat yellow" Ptocadica species nor the Dysonycha decemlineata species. But no new species have cropped up.
