Treehopper

Alchisme grossa

Description:

About 10-12mm in length, their most distinctive feature is the enlarged protonum which resembles a thorn, with two lateral spines behind the eyes. These protrusions and how they sit in single rows along plant stems or the underside of leaves, probably aids camouflage. They are green in colour, with a red band along the ridge of the protonum. The nymphs (pics #3, #4) are more light brown/cream coloured with black stripes, already showing the thorn-like protonum, but with two extra pairs of needle shaped spines.

Habitat:

Cloud forest at about 2000m above sea level, I saw them on Angel's Trumpet (Brugmansia sp) in the town of Aguas Calientes.

Notes:

The nymph on picture #4 was at a slightly higher location in the same general area. Some interesting info on Alchisme grossa's relation with host plants here https://www.researchgate.net/publication...
