Sooty Crane Fly -- Male
Sooty Crane Fly (Tipula fuliginosa) -- Male
The male and female sooty crane flies are appear very different. (They are sexually dimorphic.)
In fact, for many years they were thought to be different species, before someone figured out they were actually male and female of the same species.
One characteristic that clearly defines the male sooty crane fly is its characteristic asymmetrical male genitalia.
