Massai Point, Chiricahua National Monument These small black ants were common on chihuahua pines (Pinus leiophylla). According to James Trager they are Liometopum luctuosum, a somewhat polymorphic species that are "bitey." I can definitely testify that they bite! I originally thought they were Tapinoma sessile, but in my experience, the latter species are not "bitey." L. occidentale is our common California velvety tree ant that is very aggressive and bites. These small black ants were common on chihuahua pines (Pinus leiophylla). According to James Trager they are Liometopum luctuosum, a somewhat polymorphic species. The petiole scale of L. luctuosum is s better developed than Tapinoma. It is more upright and sharp-edged. Tapinoma has an inconspicuous, small, low scale. All images on this page copyright © W.P.
