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.
Pedician Crane Fly
A large, mottled-winged crane fly whose predatory larvae hunt invertebrates in wet mud and stream margins. Adults are often found resting on vegetation near flowing water.
Did You Know?
Unlike most crane fly larvae that eat decaying matter, its larvae are voracious predators that ambush worms and insect larvae in mud.
