Reproductive behaviour and ecology of the dendrolimnetic Hadrothemis scabrifrons (Odonata: Libellulidae)

Abstract

Oviposition in water-filled tree holes and mating behaviour of Hadrothemis scabrifrons was observed in a lowland coastal forest in Kenya. Conforming with the predominant mode of oviposition in the Libellulidae, females of H. scabrifrons touch the water with their ovipositor while hovering above tree holes. Male behaviour is opportunistic: usually males perch and patrol in clearings away from tree holes but at exceptionally large tree holes males are territorial and guard mates. Larvae and adults were found in different seasons; the species seems to be non-seasonal.
