Explanation of Names
Dolichoderinae Forel 1878
see Dolichoderus
Odorous Ants refers to the strong-smelling lactone-family of chemicals produced in anal glands of many species
in our area, 5 genera native (Dolichoderus [4 spp.], Dorymyrmex [14+], Forelius [2], Liometopum [3], Tapinoma [4, incl. 1 introduced]) and 2 adventive (Linepithema, Technomyrmex, with 1 sp. each)
our spp 1.8‒5 mm
Tapinoma sessile virtually ubiquitous, Dolichoderus temperate eastern half of continent, other genera more regional
usually warm and/or xeric; some invade houses, especially in cooler months
All have a muscular pharynx, elaborate proventriculus, and highly expansible crop, indicative of reliance on a primarily liquid diet (honeydew, nectar), but many also prey on small arthropods, or scavenge scat, carrion.
