Habitats
Hyalothyrus neleus is restricted to primary rainforest at altitudes between sea level and about 800 metres.

Lifecycle
H. neleus caterpillars feed on Inga ( Fabaceae ) and are a dirty greenish colour, with a series of prominent pale green spots along the sides, and a large shiny reddish brown head. The internal organs and digestive system are clearly visible through the translucent skin. There is no information about the pupa, but in common with other Pyrgine skippers it is likely to be dark and smooth, with the wing cases in a contrasting tone or colour.

Adult behaviour
Adults of H. neleus are social and primarily active at dusk, or on overcast days.
