Neither Worker, Nor Queen: An Ant Caste Specialized in the Production of Unfertilized Eggs
Psyche: A Journal of Entomology, Volume 102, Issue 3-4, Page 173-185, 1995., 1995 In addition to a queen and workers, colonies of the ant Crematogaster smithi Creighton from Chiricahua Mountains, Arizona, may contain one or several conspicuous “large workers” whose size, external morphology, and number of ovarioles are intermediate between that of queens on one side and that of workers on the other.

Psyche: A Journal of Entomology, Volume 101, Issue 1-2, Page 53-57, 1994., 1994 Formicoxenus quebecensis, a rare guest ant associated with Myrmica alaskensis as yet had been found only in southern Québec. Here we report on five new localities in Alberta and British Columbia. The particular features of F. quebecensis, queen and male polymorphism, correspond in both areas.

The genetic determination of alternate stages in polyphenic insects
Evolution &Development, Volume 26, Issue 5, September 2024.Research from insect models has found the genes that determine stage identity in metamorphosing insects. Variations in the onset, duration, and tissue‐specific expression of these genes can explain life history variations throughout insects, like the castes of Isoptera or neoteny in endoparasites.

Are LED lights driving the massive nuptial flight swarm of the tramp ant Technomyrmex albipes?
Entomologia Experimentalis et Applicata, Volume 172, Issue 1, Page 75-83, January 2024.We report an unusual nuisance caused by massive mating flights of a tramp ant, Technomyrmex albipes (Hymenoptera: Formicidae) in southern Taiwan. Two trapping experiments together revealed that winged individuals were attracted more by artificial lights with short wavelengths, supporting the possible connection between the unprecedented swarming and ...
