Explanation of Names
Trupanea nigricornis (Coquillett, 1899)
Identification
The dark "Y"-shaped infuscation at the wing apex has a narrow base in T. nigricornis (i.e. about equal to the widths of the "arms" of the "Y"...as opposed to about twice as wide as those arms in T. bisetosa). Also, the tip of the antenna (i.e the flagellomere) is dark (blackish) in T. nigricornis in accord with the meaning of its specific epithet (nigri- = black; cornis = horn). For more details, see Cavender & Goeden(1983) in "Print References" below.
Range
Rocky Mountains west to Pacific coast
(1)Life Cycle
Polyphagous larval seed predators in flowerheads
(2)See Also
T. bisetosa is very similar, but both males and females in that species have yellow antennae, and the base of the dark apical "Y" on the wing is wider.
