Genus - Tapinoma

Tapinoma sessile is, in reality, multiple different species. This species is currently undergoing taxonomic revision. Some colonies may have hundreds of queens, while others are monogynous. When crushed, they emit an easily identifiable odor. This is probably the easiest species in Virginia to identify with taste and smell.

Genus - Dorymyrmex

Dorymyrmex bureni, also known as pyramid ants, are notable for their mound shape. Workers are very fast and are difficult to feed in a tube. This species is monogynous and monomorphic.

Genus - Forelius

Forelius pruinosus has several different color variants.  I have only seen the black morph, but the bicolored morph can commonly be found along the coast. This species is polygynous and monomorphic.

Genus - Dolichoderus

Dolichoderus mariae

Dolichoderus plagiatus

Dolichoderus pustulatus

Dolichoderus taschenbergi

Ponera pennsylvanica is the most common Ponerine in the majority of the state. This species is small, polygynous, and has small colonies. Workers and queens can commonly be found foraging under rocks. This species flies alongside Myrmecina americana.

Ponera exotica is the smallest Ponerine in the state. With workers sitting at a miniscule 2mm, this species is uncommonly found in Virginia.

Hypoponera opacior is a small, cryptic ant that commonly flies alongside Colobopsis obliqua, Tapinoma sessile, Temnothorax curvispinosus, Temnothorax ambiguus, and Pheidole bicarinata. This species can be easily differentiated from Ponera pennsylvanica through the lack of a "tooth" under the petiole.

Brachyponera chinensis is an invasive species from East Asia. Colonies grow to massive sizes, often reaching over 5000 workers. This species is very polygynous and workers will tolerate other workers from different colonies. 

Stigmatomma pallipes workers can commonly be found foraging for centipedes in the order Geophilomorpha under rocks and moss. I have found alates during flights of Lasius murphyi, Solenopsis molesta, and Brachymyrmex depilis.

Genus - Proceratium

Pergandei clade

Proceratium pergandei

Silaceum clade

Proceratium crassicorne

Proceratium silaceum

Genus - Discothyrea

Discothyrea testacea is a very rare cryptic ant that has only been recorded a couple times in Virginia. Workers and queens are yellow/orange.

There are few records of Pseudomyrmex pallidus in Virginia. Queens and workers are small and bright yellow. As the name suggests, Pseudomyrmex nest in twigs and small branches. This species reportedly has a nasty sting.
