This is a Fossil Love Bug, one of the most satisfying fossils to collect in the Eocene deposits of Princeton, British Columbia.
Love Bugs or March Flies are hardy, medium-sized flies in the Order Diptera, with a body length ranging from 4.0 to 10.0 mm. The body is black, brown, or rusty, and thickset, with thick legs. The antennae are moniliform. The front tibiae bear large strong spurs or a circlet of spines. The tarsi are five-segmented and bear tarsal claws, pulvilli, and a well-developed empodium.
As it is with many species, these guys included, the teens of this species are troublesome but the adults turn out alright. As larvae, Bibionidae are pests of agricultural crops, devouring all those tasty young seedlings you've just planted.
Then, as they mature their tastes turn to the nectar of flowers from fruit trees and la voila, they become your best friends again. With their physical and behavioral transformation complete, Bibionidae become a welcome garden visitor, pulling their weight in the ecosystems they live in by being important pollinators.
