Synonyms and other taxonomic changes
revised in(1)
Explanation of Names
Hemipenthes Loew 1869
'half-veiled in black' (refers to the wing pattern)
Numbers
23 spp. in our area, 80 spp. worldwide(2)
Size
6-12 mm, wingspan up to 22 mm
Identification
Body dark, often with scattered pale metalic-colored hairs on abdomen and/or thorax; wings with dark leading edge; dark area of wing has irregular rear border; trailing edge of wing clear. Proboscis fairly short, does not project beyond face. Face bluntly rounded. Rear margin of eye indented. Front tibia has dark bristles.
Key to nearctic species in Ávalos-Hernández(2009)...see "Print References" below.
Range
New World (almost 2/3 of spp.) and Eurasia; in our area, all but 5 spp. are western (more diverse in sw. US), H. sinuosa e. US + AZ, H. catulina and the holarctic H. morio transcontinental in the US, H. celeris & H. floridana restricted to se. US(2)
Season
H. celeris: Jul-Sep in NC, H. sinuosa May-Sep in NC, Jun-Aug in MN(3)
Food
Ectoparasitoids in puparia of Diptera, cocoons of Ichneumonoidea, also their Lepidoptera and Diprionidae hosts. "We consider records from Bombyliidae pupae, Andrenidae and Acrididae are unreliable" (Research.net. Yeates, D. The evolutionary pattern of host use in the Bombyliidae (Diptera): a diverse family of parasitoid flies)
See Also
Chrysanthrax has similar wing pattern, but boundary is more linear (not so sinuate), plus golden hair on body
