Distribution

This taxon was described from Baltic amber (Bartonian, Middle to Late Eocene) and is also known from Bitterfeld amber (Bartonian, Middle to Late Eocene), Danish-Scandinavian amber (Bartonian, Middle to Late Eocene) and Rovno amber (Priabonian, Late Eocene) (Perkovsky, 2016).

Biology

This species is a host for the nematode Heydenius formicinus (a parasite) in Baltic amber (Poinar, 2002) (Baltic amber fossil).
