Larvae of Hadrothemis scabrifrons (Ris) in a tree cavity in East Africa (Anisoptera: Libellulidae)

Two large larvae of H. scabrifrons and 2 smaller larvae probably of this species have been found in a water-containing cavity in a tree root in lowland rainforest near the Kenya coast. Conventional collecting methods may result in large Odonala being under-represented in collections from tree holes. The oviposition behaviour of Anisoptera occupying tree holes is probably unusual and merits study.
