Species: Aedes hendersoni


This species is not known to be an important pest in Montana. Adults are not frequently collected, suggesting it is either rare or not attracted to CO2-baited light traps.


This is one of two tree-hole mosquitoes found in Montana (Ae. sierrensis is the second). Eggs are deposited inside a tree-hole. Winter is passed in the egg stage. Cavities in a wide variety of tree species serve as primary habitat for this species in forested areas. The mosquito also lays its eggs in an array of artificial containers including buckets, cans and barrels.

Identifying Characteristics:

Pointed abdomen, no leg banding, scutum with median stripe of dark scales surrounded by silvery white scales laterally.
