Perhaps because of their elongated shape, members of the fly family Therevidae have acquired the common name “stiletto flies.”
Deliberately or by accident, humans have transported many thousands of species from their native ranges to new regions or continents.
A rarely reported, carrion-loving fly turns up on the southern shoreline of Martha’s Vineyard.
An interesting species was added to the BWorks Martha’s Vineyard Atlas of Life project on iNaturalist last weekend: Vespula vidua, sometimes known as the widow yellowjacket.
