Stings of some species of Lordomyrma and Mayriella (Formicidae: Myrmicinae) [PDF]

open access: yes, 2011
The sting apparatus and pygidium are described for eight of 20 Lordomyrma species and one of five Mayriella species. The apparatus of L. epinotaiis is distinctly different from that of other Lordomyrma species.

Diversity-dependent effects probably influenced the diversification of species-rich crown ant subfamilies during the Cenozoic [PDF]

open access: yesRoyal Society Open Science
Disentangling the influence of biotic interactions from abiotic environmental changes is a central challenge in macroevolution. While ants’ evolutionary history has been widely studied, often in relation to abiotic factors or plant associations, the role

Size, Spines, and Nests: What Drives Variation in Death‐Feigning Behavior in Fungus‐Farming Ants?

open access: yesIntegrative Zoology, EarlyView.
We investigated death‐feigning (DF; thanatosis) in fungus‐farming ants, testing how stimulus intensity, morphology, and nest traits shape its occurrence and duration using generalized linear mixed models. Stronger stimuli increased both likelihood and duration, but most variation was structured across species, colonies, and individuals.

Terminal Filament Bundling Underlies the Development of Ovariole Number Dimorphism Between Queen and Worker Ants

open access: yesEvolution &Development, Volume 28, Issue 3, September 2026.
We trace the formation of the cell structures known to determine ovariole number in the model insect Drosophila melanogaster, called terminal filaments. By investigating the formation of terminal filaments and ovarioles during queen and worker development in ants, we confirm the existence of terminal filament bundling (white arrows) and show that it ...

Sibling species of the Cotesia inducta complex (Hymenoptera: Braconidae) sympatrically parasitising heterogeneous lycaenid larvae associated with ants

open access: yesEntomological Science, Volume 29, Issue 3, September 2026.
Three sibling parasitoid wasps of the Cotesia inducta (Braconidae) complex attack ant‐associated lycaenid larvae in Japan. Species differ in host range, seasonal host use and feeding habitat. Differences in host‐feeding habitat may contribute to diversification within the Cotesia inducta complex. Abstract Approximately 75% of lycaenid butterfly species
