The Three Spot Grass Yellow, Eurema blanda snelleni (Moore)

Characterised by the presence of 3 cell spots on the undersides of the wings. However, this guiding point for identification can be confusing as it is a variable species and can display vestigial third spot on the FW cell. Largest by wingspan of the Eurema.

The gregarious larvae are voracious feeders and can easily deplete branches of leaves...Above the large final instar caterpillars.



The pupa has a range of colours from grassy olive to darker brown
