About Osca lata (Guérin, 1835)
Osca lata, commonly called coliguacho, tábano, or black horse fly, is a large species of horse fly. Its natural distribution covers southern Chile and southern Argentina. This species was previously classified under the name Scaptia lata. It has a distinctive striking reddish-orange coloration on the sides of its thorax and abdomen. Full-grown adult individuals are typically around 2 centimeters in size. As with most horse fly species, female Osca lata must feed on mammalian blood before they are able to produce eggs.
