White-spotted Pond Fly
Sericomyia lata is a syrphid fly commonly known as the White-spotted Pond Fly. Adults are medium-sized hoverflies, 11.6–15.2 mm in length, with distinctive black bodies and large white abdominal spots. The species is widespread across North America, with highest concentrations in eastern regions. Like other members of its genus, the larvae develop in aquatic or semi-aquatic habitats and possess the characteristic rat-tailed breathing siphon typical of Sericomyia.
