The offspring of different females make contact with each other and form mixed groups. Acanthostomatidae Zool Anz Jena Citing articles via Web of Science The ovary structure in the studied species differs from that found in other Heteroptera.
In other projects Wikimedia Commons Wikispecies. We manipulated clutch size by removing small and large females from their own eggs and giving them another clutch. The ovaries of this species are structured to enhance this behavior. Males are smaller than females. Each ovariole contains only one growing ovarian follicle.

We conclude that an ecological factor predation limits lutch size in this species and the parent bug lays an optimal clutch size as determined by the defending ability of the female.

After oviposition, the parent bug female stands over the egg batch and shields it throughout egg development.
Modeling the functional link between movement, feeding activity, and condition in a marine predator. Considering that the older nymphs are more mobile and may escape from predators, some offspring of the parasited females of the parent bug probably survive and may also be potential hosts for the new generation of the parasite.

However, when the clutch size was manipulated, small females protecting large clutches lost significantly more eggs than large females guarding small clutches or females in the control groups guarding clutches of optimal size.
These medium-sized shieldbugs are usually brown-reddish, but there are also gray hence the Latin species name grisea and green-brown specimen.
