Mes de las moscas de la familia Bombyliidae: Abril 2023.
Mosca de la subfamilia Bombyliinae (Número: 23), perteneciente al género Sericosoma, libando flores del ( Haplopappus velutinuss ).
Interrelación Floral: Sericosoma sp. - ( Haplopappus velutinus ) .
Significantly larger than other Phthiriinae that I've seen. Feeding from wallflower.
I expected this to be one of the Lepidophora bee flies when I first saw it, but quickly realized the abdomen was completely different. It looks superficially like Toxophora amphitea, but there are no iNaturalist observations for that species in Missouri. I have a lot of additional images if a particular view would help.
The photos all seem to show a pale yellowish cast on the posterior dorsal abdomen, but in the field I thought it looked closer to whitish. I suspect the camera picked up reflected light from all the Rudbeckia, but maybe my eyes were playing tricks on me.
