Name
Ega Laporte de Castelnau, 1835 – Wikispecies link – Pensoft Profile
- Ega Laporte de Castelnau, 1835: 93
Type species
Ega formicaria Laporte de Castelnau, 1835: 93
Way of life
Size range – 2.8 mm to 4.7 mm; species of this genus not only have color patterns and movements like ants, they have body constrictions, giving them ant-like proportions, even more so than their probable adelphotaxon, Calybe. They live near water bodies usually on steep slopes above the water on damp clay soils, in the company of similar-sized ants. They catch small arthropod prey on the run much like tiger beetles. Identification is very difficult without recourse to types; the genus is in need of a taxonomic revision.
Distribution
Southern USA (CA to GA, FL) south to Argentina. Not known from the Caribbean islands.
Notes
Currently, 17 described species are assigned to this genus, some of which are likely Calybe species; however, many more true Ega species are represented in the NMNH collection. A taxonomic revision of the group is needed. Identification of species is impossible without recourse to types.
