Mango Planthopper - Colgaroides acuminata

Family Flatidae 

This page contains pictures and information about Mango Planthoppers that we found in the Brisbane area, Queensland, Australia. 

Body length 18mm
Planthoppers are close related with cicada. They are plant suckers. This Planthopper is creamy green in colour with a tiny pink dot at the middle of each front wing. They are common in Brisbane and can be found on stem of different plants. They are considered as pest in the mango growing industry.

They look like green triangular plant spines when they rest on the tree stems. Their broad triangular forewings held roof-like over their body make them easily recognized.

At first we wrongly identified them as Siphanta sp.. Dr. Murray Fletcher send us email and advised that "The flatid image identified as Siphanta sp. on your website is actually Colgaroides acuminata. Species of Siphanta have the head flat dorsally with a distinct horizontal carina between the vertex and face. The conical head shape of the specimen in your picture is typical of Colgar and Colgaroides, which can be differentiated from each other by the number of vertical carinae on the face."
