Driftless Prairies: Native Habitat Restoration

Nature inspires awe!

Staphylinidae (Rove Beetles)

This is the least known beetle even though more than 40,000 species have been described worldwide; a prediction is that there could be over 100,000 species. In North America, this is the 2nd largest family with over 3,000 species.

Rove beetles are predacious but some will feed on fungal spores or pollen. They don’t come out in the day often, preferring to be in soil, leaf litter, or under bark. The larvae are restricted to the moist and concealed habitat.

Rove beetles can live in ant nests without being attacked. They have evolved a way of imitating how the ant begs so worker ants will feed them. This would not be sufficient without their ability to mimic the pheromone that ant larvae produce.

Eggs are round, white or almost white. They are usually laid singly, dropped onto the substrate but with all insect information, there are exceptions.
