• Disholcaspis prehensa

  clasping twig gall wasp

  Disholcaspis prehensa is a gall-inducing cynipid wasp native to California that induces distinctive galls on scrub oak and leather oak. The species exhibits heterogony, alternating between sexual and asexual generations that produce two morphologically different gall types. The asexual generation forms conspicuous mushroom-shaped twig galls with clasping bases, while the sexual generation produces small, hidden bud galls.

• Pentodontini

  rhinoceros beetles

  Pentodontini is the most diverse tribe within the subfamily Dynastinae (rhinoceros beetles), containing over 100 genera distributed across multiple biogeographic regions. Most genera are restricted to a single biogeographic region. The tribe is characterized by substantial morphological diversity, with generic-level identification often relying on mouthpart morphology in females and secondary sexual characters (horns, claw modifications, antennal club length) in males.
