Green-leaf Mimic Katydid

Typophyllum sp


Tettigoniidae family. The body of this Katydid was about 6-8 cm long. The body had the shape of a green leaf including the middle stem (petiole) and veins. It even goes so far as to imitate a diseased or damaged leaf with holes and spots. The antennae are dark and the head and parts of legs are gray. The rest of the body as well as the front of the head are green.


This one was found in a wooden house in the Amazon rainforest of SE Ecuador (700 masl). It doesn't really blend in all that well with a blue waste basket so I don't think that is probably its natural habitat :-)


Most tettigoniids eat plants although there are a few that prey on other insects. This Katydid had been tangled in cobwebs and was in some difficulty. I cleaned it off, put it back on the wastebasket for pictures and put him outside. The leaf mimicry is amazing.

Thanks so much Roy. I believe you have at least identified the Genus. I see there are 38 species listed on Wiki, none of which have fotos, descriptions or ranges. While the photo on T. erusum does look like mine, I'm going to hold off for a little before putting the species. I really appreciate this lead. I was getting nowhere.

Thanks Amadeus & Sukanya. If they don't move, you'd never see them (unless they're on a blue waste basket) :-)

What a lovely coincidence...I was writing on Camouflage as a survival strategy and of course mentioned the Leaf Katydid...and then I saw your spotting!!!! Thanks.

Wonderful spotting Tukup. Hard to believe it's a critter and not a leaf :D Thank you for sharing.

That is spectacular. I was looking for the critter in the first photo, not realising that was the critter. Nature never ceases to amazing! Very well spotted, Tukup.

Thanks Zlatan. I'm finding plenty of examples on internet, but none with any classification.
