Species polyethism in heterospecific groups of Myrmicinae ants

Ethology Ecology and Evolution, 1995
We studied species polyethism in heterospecific queenless and queenright groups of ants by associating Manica rubida (olygogynous) individuals with Myrmica rubra (polygynous) and Myrmica ruginodis (monogynous) individuals, respectively. In queenless and queenright groups, Myrmica workers specialized in brood care and guarding the nest while Manica ...

A new pheromone in the ant Pheidole pallidula (Myrmicinae)

Behavioural Processes, 1991
In the dimorphic species Pheidole pallidula, an ethological factor, present on the VIIth abdominal sternite attracts ants from short distances and enhances the linear speed of those having approached it. Added to poison gland extract, it improves the workers' trail following behaviour.

Direct homing behaviour in the antTetramorium caespitum(Formicidae, Myrmicinae)

Animal Behaviour, 1998
Direct homing refers to the behaviour whereby an ant with food runs in an almost straight line to the nest. We determined whether non-polarized light acts as a directional cue in the direct homing behaviour of the grass ant, Tetramorium caespitum. We carried out tests (1) under a blue sky or in total overcast conditions in the field, and (2) with a ...

The Male of the Ant Genus Rhopalothrix (Hymenoptera: Formicidae: Myrmicinae)

Neotropical Entomology, 2022
The male caste is firstly described for the ant genus Rhopalothrix. The male was collected as attached to the gyne during copula. Due to the rarity of the genus, the gyne and male are tentatively associated with R. apertor Longino and Boudinot 2013. The apomorphic features of Rhopalothrix male are discussed, and a preliminary identification key based ...

Taxonomic revision of the Neotropical Myrmicinae ant genus Blepharidatta Wheeler

Zootaxa, 2015
We revise the taxonomy of the exclusively Neotropical Myrmicinae ant genus Blepharidatta (Attini), redescribing the known species (B. brasiliensis and B. conops), and describing two new species, B. delabiei sp. n. (Brazil: Bahia) and B. fernandezi  sp. n. (Colombia: Amazonas). We also describe worker sting apparatuses, larvae, males, and ergatoid gynes

Mating behavior in the ant, Myrmecina graminicola (Myrmicinae)

Insectes Sociaux, 2003
Sexual behavior of Myrmecina graminicola in laboratory conditions is described. Virgin females, both gynomorphs and intermorphs, exhibit an inconspicuous "sexual calling", apparently depositing a sex pheromone on the substrate close by. The sexual pheromone is produced in the poison gland.
