Myrmica scabrinodis scabrinodis
''Myrmica scabrinodis scabrinodis'' is a subspecies of ant that can be found everywhere in Europe except for Andorra, Bosnia and Herzegovina, Canary Islands, Croatia, Iceland, Malta, Monaco, Madeira, Monaco, San Marino, Slovenia, and Vatican City.〔(【引用サイトリンク】title=Myrmica scabrinodis scabrinodis Nylander, 1846 )〕 It is unique in that it reproduces by ejecting pheromones from its postpetiole directly into the mandibles of its mate. Female ants of this species can also reproduce through thelytokous parthogenesis, but, unlike most ant species during this process, the individual will rupture the membrane of the gaster, causing a burst of secretions containing their offspring in addition to acetophenones and other chemicals.〔(【引用サイトリンク】title=A Population Study of the Ants Myrmica Scabrinodis )〕
Oleic acid has been identified as the compound released from dead ants that triggers necrophoric behaviour in genus ''Myrmica'', however ''M. scabrinodis scabrinodis'' occasionally respond by engaging in anthropophagy. Males in this species react to the absence of characteristic chemicals (dolichodial and iridomyrmecin) present on the cuticle of their living nestmates to trigger a similar response. About 12%, 16%, and 4% of their faecal volume in spring, summer, and autumn, respectively, is composed of material from this behaviour.〔(【引用サイトリンク】title=A Study of the Behaviour of Mordibund Ants )〕
