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.
Miles' Longhorn
A large dark brown longhorn found in old oak forests around the Mediterranean basin, often confused with C. cerdo but distinguished by the sculpture of its elytra. It is nocturnal and attracted to fermenting fruit bait.
Did You Know?
This species preferentially attacks cork oaks, and its galleries can reduce the commercial value of cork bark.
