Lasius illyricus

Information on the ecology and biology of this species is very scarce. Ecological segregation from Lasius emarginatus due to slightly different habitat preferences is witnessed in Greece (Borowiec & Salata, 2013), but no information is available from regions in which L. emarginatus is probably absent (Schifani & Massa, 2020).
