A comparative analysis of the ovary structure during the life cycle, particularly the presence of atresive ovarian follicles in the ovarioles of egg- and nymph guarding females, as well as the shape and structure of the apical part of the tropharium all support the hypothesis of cooperation between females in E.

Description Elasmucha grisea Parent bugArnhem, the Netherlands – 3. The common name of Elasmucha grisea comes from the relatively rare insect behaviour of prolonged caring for eggs and juveniles, exhibited by females of this species.

Larvae are likely to benefit from ‘kindergartens’, when their mothers disappear or die. This file is made available under the Creative Commons CC0 1. In other projects Wikimedia Commons Wikispecies.
