Trophic eggs compensate for poor offspring feeding capacity in a subsocial burrower bug.

Various animals produce inviable eggs or egg-like structures called trophic eggs, which are presumed to be an extended maternal investment for the offspring. However, there is little knowledge about the ecological or physiological constraints associated with their evolutionary origin. Trophic eggs of the seminivorous subsocial burrower bug (Canthophorus niveimarginatus) have some unique charact...

Maternal hatching synchronization in a subsocial burrower bug mitigates the risk of future sibling cannibalism

Sibling cannibalism-the killing and consumption of conspecifics within broods-carries a high risk of direct and inclusive fitness loss for parents and offspring. We reported previously that a unique vibrational behavior shown by the mother of the subsocial burrower bug, Adomerus rotundus (Heteroptera: Cydnidae), induced synchronous hatching. Maternal regulation may be one of the most effective ...

Maternal Vibration: An Important Cue for Embryo Hatching in a Subsocial Shield Bug

Hatching care has been reported for many taxonomic groups, from invertebrates to vertebrates. The sophisticated care that occurs around hatching time is expected to have an adaptive function supporting the feeble young. However, details of the characteristics of the adaptive function of hatching care remain unclear. This study investigated the hatching care of the subsocial shield bug, Parastra...

Offspring-parent Communication in a Subsocial Treehopper (hemiptera: Membracidae: Umbonia Crassicornis)

Parental care of post-hatching offspring is widespread in insects, but the role of communication in parent-offspring interactions remains largely unknown. I have found that, in the subsocial treehopper Umbonia crassicornis, aggregated nymphal offspring produce substrate-borne, vibrational signals in synchronized bursts that elicit the mother’s antipredator behavior. In this study I describe the...
