At a Glance • Temporary parasite  

 

Identification

Similar in appearance to Lasius interjectus, but averaging and ranging smaller. Body pilosity very sparse and long; gula usually with no standing hairs, occasionally with 1 inconspicuous short hair, rarely with 2 or 3 standing hairs. Pubescence very dilute, especially on gaster; body surface highly glabrous. Worker Dorsum of propodeum convex, often strongly so. Crest of petiolar scale sharp to moderately sharp, weakly to strongly emarginate. Color, yellow to yellowish brown. Queen Crest of petiolar scale sharp to moderately sharp, weakly to strongly emarginate. Color reddish brown. Male Crest of petiolar scale sharp to very sharp; emarginate, straight or convex. Color, dark brown. (Wing 1968)

Biology

Wing (1968) summarized the following natural history information and the alate dates given below. Almost no biological data have been published on Lasius arizonicus. Wheeler (1917) cited 3 localities in Cochise Co. from which the types were collected, giving an altitude of 5000 ft. for one collection. Data associated with the specimens at hand are meager. Four samples were taken under stones, 1 came from a "shaded canyon". Slightly over 20 samples had altitudinal data. With the one exception of a collection made at 2000 ft., they ranged from approximately 5000 to 8500 ft.

Reproduction

Alate dates Eight dated samples contained alates. The extreme dates are June 13 and August 8. On June 13, queens alone were captured on 2 occasions. Dealate queens were taken on July 6 and 8. It is likely that flights begin by mid-June. The collection on August 8 contained workers and males; it is probably a nest collection. Thus flights may still occur as late as early August.

This species is likely to be a temporary parasite, but its host is unknown.
