Parental care and offspring survival in Copris incertus Say, a sub-social beetle
Article Abstract:
Absence of maternal care reduces offspring survival in Copris incertus Say, a sub-social beetle, with the effect being most significant in the transition from the pupa to adult stage. Frequent care of the brood balls by the mothers prevents fungus infection and protects the soil layer from damage. The mother also protects the nest from intruder attacks. This in turn increases offspring survival. Sub-social care, especially during the vulnerable developmental stages, reduces the mortality rate of the offspring.

Male horn dimorphism in the scarab beetle, Onthophagus taurus: Do alternative reproductive tactics favour alternative phenotypes?
Article Abstract:
Alternative reproductive tactics used by male scarab beetles, Onthophagus taurus, were examined. It is suggested that such alternative tactics selectively favour discretely different male phenotypes. Horn possession is found to confer an advantage to males using fighting behaviors to access females, while hornlessness could be favoured by males that depend mainly on sneaking behaviors.

Antennal asymmetry and sexual selection in a cerambycid beetle
Article Abstract:
The exaggerated antennae displayed by cerambycid beetles are thought to be related to sexual success. A new study investigates sexual selection and antennae morphology in the species Stenurella melanura, in which the antennae of males are 13% longer than female antennae. Results suggest that antennal symmetry is more important than length in sexual selection.
