Identification
Keys to genera in
(3)(5)(4)
Fore wing M+CU not tubular in basal 1/3 or more
Fore wing 3RSb terminating at wing margin near stigma and distant from wing apex
Habitat
Most terrestrial habitats.
Agathis and
Earinus are more species-rich in temperate regions. In
Agathis and
Crassomicrodus, some species tend toward desert habitat. Other genera most diverse in humid tropics.
(6)Food
hosts: Lepidoptera larvae
Remarks
species useful for pest control in our area include Agathis pumila against larch casebearer; A. stigma and Cremnops laricella against sugarcane borer; & Bassus unicoloratus against potato tuberworm.
"There are three main Agathidine genera with the 'long face' (
Agathus, Bassus, and
Cremnops).
Agathus is almost always entirely black, whereas
Bassus and
Cremnops are red & black.
Cremnops has a carina extending from the lateral margin of the antenna to the lateral ocelli. The carina is absent in
Bassus." (Comment by M.J. Sharkey, 2007).
