Ceresa diceros |
| description |
A very distinctive looking member of this genus with prominent pubescence (hair) on the front of the pronotum (characteristic of this species); the front of the pronotum is yellowish with numerous scattered brown markings. The pronotum is dark brown with transverse bands of yellowish white; sometimes the bands do not transverse all the way across the pronotum, with pale patches on the sides of the pronotum instead, and the brown pattern can vary among individuals. The humeral horns are stout and blunt, and the legs vary from light to dark brown; the underside of the body is a very dark brown. The wings are a smoky to dark brown hyaline. Adults are 8 to 9 mm long, with females larger than males; the width between the humeral horns is 5.5 mm. (FSCA), (Kopp & Yonke, 1973)

| behavior |
To listen to the male courtship call for this genus, listen here. These courtship calls are not audible to the human ear, and the calls here are produced by recording the substrate vibrations that the treehoppers use to communicate through the plants themselves. The recorded call is then amplified so that it is now audible to human ears. Research has shown that treehoppers use vibrations to attract mates, to announce the discovery of a good feeding site, or to alert a defending mother to the approach of a predator (T.IM). |
| comments |
Can be attracted at night with a light.
S. diceros is a fairly distinctive member of this genus, but the fairly uncommon S. albescens is the most similar species. In albescens, the pronotum is scantily hairy and has one definite tan band near the apex; in diceros, the pronotum is very pubescent and has 2 well defined dark brown bands with a pale, tan area in between. (Kopp & Yonke, 1973) |
