Spilomyia larva? - Spilomyia citima
Pullman , Whitman County, Washington, USA
March 23, 2010
Size: 1.5 cm
I found this among a dozen or so in a tree hole. I took 4 to try to hatch out. One appears to have hatched while I was away for several days (the main photo in this submission). It took 2 1/2 months to hatch. The larvae undulate in the water with the narrow end at the air/water interface. When the water level is low, they move along the bottom of the container with by contraction and extension.
