Olfactory System Morphology Suggests Colony Size Drives Trait Evolution in Odorous Ants (Formicidae: Dolichoderinae)
- BiologyFrontiers in Ecology and Evolution
Results do not find evidence supporting a universal pattern of sensory system scaling associated with changes in colony size, but it is hypothesized that observed differences in the olfactory components in two closely related Dorymyrmex species are evidence of a link between colony size and sensory trait evolution.
Intracolony vibroacoustic communication in social insects
- BiologyInsectes Sociaux
This review describes the modalities and their behavioral contexts rather than electrophysiological aspects, therefore placing emphasis on the adaptive roles of vibroacoustic communication.
Age‐related changes in the number and structure of synapses in the lip region of the mushroom bodies in the ant Pheidole dentata
- BiologyThe Journal of comparative neurology
Findings indicate an expansion and enhancement of efficacy at specific sets of synaptic connections between the projection interneurons and Kenyon cell dendrites and a commensurate loss of other connections as minor workers age and expand their behavioral repertoire.
A new putative species in the Ectatomma ruidum complex (Formicidae: Ectatomminae) produces a species-specific distress call
The results highlight the use of acoustic traits as potential taxonomic tools for integrative taxonomic studies and suggest that the acoustic traits of E. ruidum species complex have been subjected to selection.
Stridulatory organ and distress call in males and females of a small velvet ant (Hymenoptera: Mutillidae)
Stridulation patterns and stridulatory organ were rarely investigated in the parasitoid family Mutillidae, and data still lack for any sex or species in many subfamilies. We described the morphology…
Honey bee stop-signal production: temporal distribution and effect of feeder crowding
The colony produces stop-signals at a baseline level that can be elevated in response to crowded foraging conditions, and it is found that bees returning from uncrowded feeders also produced stop- signals.
The vibration signal, modulatory communication and the organization of labor in honey bees, Apis mellifera
The empirical evidence that the vibration signal is involved in coordinating at least three colony-level activities: food collection and foraging-dependent tasks, queen behavior during swarming and queen replacement, and house hunting by honey bee swarms is reviewed.
Diversity, distribution and secrets of ant transportation networks
- Environmental ScienceJournal of Entomology and Zoology Studies
One of the most striking examples of transport networks are the trail systems formed and used by several species of ants. Ants forage to find food from a central nest, building a network of trails…

Ancestral state reconstruction suggests repeated losses of recruitment communication during ant evolution (Hymenoptera: Formicidae)
The ability to robustly identify patterns in the evolution of communication in ants remains hampered by a lack of natural history information for most ant species, so the results are consistent with the finding that early ants lived in colonies containing up to several thousand individuals.
