Explanation of Names
Epuraea Erichson 1843
32 spp. in our area(1) (the number is expected to change), perhaps close to 200 worldwide, arranged into 17 subgenera(2)
Often requires examination of male copulatory organs; however, several common spp. can be IDed with high degree of certainty based on habitus -- 23 spp. are imaged in(3)(4)
Worldwide except S. America; the Holarctic fauna is the richest(5); in NA, across the continent(1)
On sap, fungi, rotting fruit; some on flowers, in bee (esp. bumblebee) nests, or leaf litter(5)
