Lobster Cockroach
A small to medium cockroach with mottled grey-brown coloring that is widely used in scientific research and as feeder insects. It communicates using pheromones.
Did You Know?
Male lobster cockroaches establish dominance hierarchies using chemical signals, and subordinate males alter their pheromone profiles to avoid confrontation.
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.
