Pycnopalpa katydid nymph

Pycnopalpa sp., most likely P. bicordata


Another extraordinary katydid nymph. This girl (it has an ovipositor, so it is a "she") is so incredibly shaped that I won't even try to describe it. Its most distinctive feature is that it keeps the rear femurs extended forward, parallel to the surface it is in, instead of keeping them pointed upwards, as usual in other katydids.


Family Tettigoniidae, Subfamily Phaneropterinae,

Acredito que sua defesa tem a ver com os benefícios da aparência similar de uma borboleta, ou melhor, pequena mariposa. Foi o que vi na primeira vez; Vou fotografar esta mariposa pequena; após é que descobri que era um gafanhoto.

Lauren, in order: First, yes, it has an ovipositor, so it is a she; second, it is a nymph, so I believe it is not sexually mature yet; third, l am sorry, but have no idea what advantage it has looking like that. Maybe, its look helps it to run away while their possible enemies try to figure out what the hell it is, and if it is eatable or not... :-)

It definently has an ovipositor, is she sitting on an egg mass and that's why she looks so bizarre?

fantastic, it reminds me of some orchid-flowers... maybe it's attracting other insects and is as many katydids insectivorous ...
