Gratidia hispidulus (PSG 183)

   Phasmids of this species can range in color from beige to green.  They have short antennae, and are rather short stick-insects (measurements will be added later).  These pictures are of specimens through the 4th instar, with the final instar bringing the most drastic changes in appearance (for most species, usually).  The nymphs have small spikes on the sides of the thorax at this stage, and some develop red lines which span this area as well.  Ova are glued to everything in the cage, even each other.

Foodplants:  bramble, oak, raspberry, red maple
