Lasiopogon bivittatus mating pair - Lasiopogon canningsi - Male Female
Trinidad State Beach, Trinidad, Humboldt County, California, USA
May 15, 2012
Size: 12 mm
These are common on the beach dunes of northern California and Oregon in April-June. They perch on the bare sand next to patches of vegetation. They can be found on any of the dunes (i.e., both the 1st dune and subsequent ones), but I think they're more common on the interior dunes. Black haired, with prominent dorsocentral stripes and tergites mostly polished.

new species
This population of extreme northern Californian bivittatus is now split into a new species (Lasiopogon canningsi) in the new monograph I wrote with Rob Cannings (though the species authority is just mine-- don't worry, he didn't name a species after himself!) The full citation for the paper is:

McKnight, T.A. & Cannings, R.A. (2020) Molecular phylogeny of the genus Lasiopogon (Diptera: Asilidae) and a taxonomic revision of the bivittatus section. Zootaxa, 4835(1), 1–115. https://doi.org/10.11646/zootaxa.4835.1

Email me if you'd like a copy of the PDF.

In our understanding, true L. bivittatus is only found in the San Francisco / Marin Co. area, and can be differentiated by slightly wider white bands on the tergites, a few different patterns of white and black hairs on the thorax and tergite 1, and a differently shaped cutout on the epandrium apex. This species (L. canningsi) does extend just over the border to Curry Beach, OR, but the mid-Oregon populations are split into another new species (L. tumulicola).
