Claviger is a genus of beetles in the family Staphylinidae, subfamily Pselaphinae. About 40 species and subspecies are described, divided into two subgenera, Claviger (Claviger) and Claviger (Clavifer). [1] [2] Claviger displays unusual biological adaptations to myrmecophily. This pselaphid is of palearctic distribution.

Animal cognition encompasses the mental capacities of non-human animals including insect cognition. The study of animal conditioning and learning used in this field was developed from comparative psychology. It has also been strongly influenced by research in ethology, behavioral ecology, and evolutionary psychology; the alternative name cognitive ethology is sometimes used. Many behaviors associated with the term animal intelligence are also subsumed within animal cognition.
Flower chafers are a group of scarab beetles, comprising the subfamily Cetoniinae. Many species are diurnal and visit flowers for pollen and nectar, or to browse on the petals. Some species also feed on fruit. The group is also called fruit and flower chafers, flower beetles and flower scarabs. There are around 4,000 species, many of them still undescribed.
Carabus is a genus of beetles in family Carabidae. The genus is highly diverse with 94 subgenera, 897 species and 2300 subspecies, thus is the largest genus in the subfamily Carabinae. The vast majority are native to the Palearctic, but 11 Nearctic species are also known. Carabus spp. are 12–50 mm (0.47–1.97 in) long, and most species are wingless and often very colourful. These are nocturnal, predatory beetles that feed on snails, earthworms, and caterpillars.
Pterostichus is a very large genus of ground beetles with a Holarctic distribution in the subfamily Harpalinae. It has over 1,100 species. The beetles are predatory, but sometimes feed on strawberries. They can be found under rocks and prefer slightly moist, sandy soil although preferences differ between species.
Trechus is a genus of ground beetle native to the Palearctic and the Near East. The name is derived from the Greek word trécho, meaning "I run".
Many species of Staphylinidae have developed complex interspecies relationships with ants, known as myrmecophily. Rove beetles are among the most rich and diverse families of myrmecophilous beetles, with a wide variety of relationships with ants. Ant associations range from near free-living species which prey only on ants, to obligate inquilines of ants, which exhibit extreme morphological and chemical adaptations to the harsh environments of ant nests. Some species are fully integrated into the host colony, and are cleaned and fed by ants. Many of these, including species in tribe Clavigerini, are myrmecophagous, placating their hosts with glandular secretions while eating the brood.
Social immunity is any antiparasite defence mounted for the benefit of individuals other than the actor. For parasites, the frequent contact, high population density and low genetic variability makes social groups of organisms a promising target for infection: this has driven the evolution of collective and cooperative anti-parasite mechanisms that both prevent the establishment of and reduce the damage of diseases among group members. Social immune mechanisms range from the prophylactic, such as burying beetles smearing their carcasses with antimicrobials or termites fumigating their nests with naphthalene, to the active defenses seen in the imprisoning of parasitic beetles by honeybees or by the miniature 'hitchhiking' leafcutter ants which travel on larger worker's leaves to fight off parasitoid flies. Whilst many specific social immune mechanisms had been studied in relative isolation, it was not until Sylvia Cremer et al.'s 2007 paper "Social Immunity" that the topic was seriously considered. Empirical and theoretical work in social immunity continues to reveal not only new mechanisms of protection but also implications for understanding of the evolution of group living and polyandry.
Symphiles are insects which live as welcome guests in the nest of a social insect by which they are fed and guarded. The relationship between the symphile and host may be symbiotic, inquiline or parasitic.
Batrisodes is a genus of ant-loving beetles in the family Staphylinidae. There are at least 80 described species in Batrisodes.
Omalium is a genus of ocellate rove beetles in the family Staphylinidae. There are at least 70 described species in Omalium.
Astenus is a genus of rove beetles.
