Large Poplar Longhorn
A large grey-yellow lamiin covered in dense ochre pubescence, found across Eurasia in poplar-dominated habitats. It is a significant pest of poplar plantations, with larvae boring into the lower trunk. Adults are nocturnal.
Did You Know?
Heavy infestations at the base of poplar trunks can cause them to snap in windstorms.
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.
