The larvae had not been there the night before. The larvae were Apocephalus borealis, a parasitoid fly known to prey on bumblebees and wasps. The phorid fly lays eggs on the bee's abdomen, which hatch and feed on the bee. Infected bees act oddly, foraging at night and gathering around lights like moths. Eventually, the bee leaves the colony to die.
Apocephalus borealis is a species of North American parasitoid phorid fly that attacks bumblebees, honey bees, and paper wasps.This parasitoid's genus Apocephalus is best known for the "decapitating flies" that attack a variety of ant species, though A. borealis attacks and alters the behavior of bees and wasps.

Unlike butterflies, bee flies hold their proboscis straight, and cannot retract it. Many Bombyliidae superficially resemble bees and accordingly the prevalent common name for a member of the family is bee fly. [2] Possibly the resemblance is Batesian mimicry, affording the adults some protection from predators.
From ticks to spiders to bed bugs, here’s what the most common bug bites look like in photos, the symptoms to know, and whether or not they can be dangerous.
What they look like: Chiggers, a type of small mite, typically leave clusters of bites that are often very itchy. In many cases, chigger bites appear as small, red and itchy bumps. Sometimes, they ...
Bombylius major (commonly named the large bee-fly, the dark-edged bee-fly or the greater bee fly) is a parasitic bee mimic fly. B. major is the most common type of fly within the Bombylius genus. The fly derives its name from its close resemblance to bumblebees and is often mistaken for them.
The pupa is a tough capsule from which the adult emerges when ready to do so; flies mostly have short lives as adults. Diptera is one of the major insect orders and of considerable ecological and human importance. Flies are major pollinators, second only to the bees and their Hymenopteran relatives.
Honey bees are incredibly social insects. They live together in big groups with other bees in an organized society that scientists call eusocial, which means every bee has a job to do. This could ...
