Variation in the Start of Nest Abandonment in the Subsocial Shield Bug Parastrachia japonensis (Hemiptera: Parastrachiidae)

Females of the shield bug Parastrachia japonensis Scott provision their nymph-containing nests with drupes of the single host tree, Schoepfia jasminodora Sieb, and it is revealed that younger independent nymphs were rarely able to succeed in reaching the foraging site from the nest site.

Dispersal behaviour in a subsocial spider: group conflict and the effect of food availability

Timing of the appearance of the developmental characters (second moult, predation activity, agonistic behaviour against siblings, reduction of group cohesion, dispersal) suggests that the dispersal trait might have evolved in consequence of these different functional behaviours.

Provisioned Parastrachia japonensis (Hemiptera: Cydnidae) nymphs gain access to food and protection from predators

Selective provisioning of good-quality drupes by female P. japonensis, a semelparous species, was necessary for young nymphs to obtain enough food for their development and significantly reduced early mortality in the presence of a predator.

Nymphal occurrence pattern and predation risk in the subsocial shield bug, Parastrachia japonensis (Heteroptera: Cydnidae)

Parastrachia japonensis (Heteroptera: Cydnidae) is a subsocial shield bug: females guard eggs and nymphs against predators, and provision their nymph-containing nests with drupes of the single host

Juvenile hormone‐mediated reproduction in burying beetles: From behavior to physiology

The burying beetle, Nicrophorus orbicollis, is the first beetle exhibiting parental care for which endocrinological studies have been initiated, and parental care has evolved in at least 16 additional families within the Coleoptera.

Functional Value of Matriphagy in the Spider Amaurobius ferox

The estimated reproductive outputs of the alternative maternal strategies suggest that mothers of A. ferox that are cannibalized by their broods enjoy greater reproductive success than those that escape cannibalism and produce second clutches.

Quantitative composition of the defensive secretion ofBledius species (Coleoptera: Staphylinidae: Oxytelinae) is adapted to naturally occurring predators

By combining the solvents in certain ratios, the capability of cuticular penetration and therefore the effectiveness of the defensive secretions are adapted to their natural targets.

Distribuição espacial e temporal de espécies de Bledius (Coleoptera, Staphylinidae) em praias arenosas no sul do Brasil

Investigation of Staphylinidae beetles sampled along two sandy beaches in Pontal do Parana, Brazil found species showed a clear spatial separation related to different environmental requirements that enable their co-occurrence within the same beach, due to environmental variations during the year.



Distribution and abundance of the intertidal saltmarsh beetle, Bledius spectabilis

It is suggested that these beetle aggregations may play an important role in the development of the saltmarsh and the zonation of marine animals from rocky shores.

Pitfall Trapping as a Method for Studying Populations of Carabidae (Coleoptera)

Pitfall traps provide a convenient method of investigating the ecology of adult Carabidae and have been used in studies on such topics as the seasonal incidence of adults, the spatial pattern of

Convergence Patterns in Subsocial Insects

In the insects, parental behavior lies at the core of all levels of insect sociality and has arisen independently in at least 13 different orders, and Wilson (172) has identified four environmental "prime movers" that create conditions favorable to the evolution of parental care.
