Hawaiian Picture-wing Fly (Silvestris)
A Hawaiian picture-wing fly closely related to D. heteroneura but with a normally shaped head. It is found in wet forests on Hawaii Island. This species and D. heteroneura are a classic study system for understanding speciation in progress.
Did You Know?
D. silvestris and D. heteroneura can hybridize in the lab, providing key insights into how new species form through sexual selection.
Siam Crown Moth
A large silk moth closely related to the Atlas moth with warm cinnamon-brown wings and distinctive angular wing tips. The wing pattern features complex marbling and translucent triangular windows.
Did You Know?
The translucent wing windows are thought to help confuse predators by allowing the background to show through, breaking up the moth's silhouette.
