Description of the larvae of<i>Dicronocephalus wallichi bourgoini</i>Coleoptera: Scarabaeidae: Cetoniinae) with observations on nesting behavior and life cycle of two<i>Dicronocephalus</i>species under laboratory conditions

Abstract

Abstract Larva of the fruit beetle Dicronocephalus wallichi bourgoini Pouillaude 1914 is described and illustrated. The following unique morphological characters within Cetoniinae are discussed: shape of claw, spindle-shaped last antennomera, general body shape. The presence of metathoracic egg-bursters in the first instar larva has been found. Its significance for distinguishing the first instar larvae of Cetoniinae is discussed. The nesting behaviours of D. wallichi bourgoini and D. adamsi(Pascoe 1863) are described. The course of the life cycle of both species under laboratory condition is presented and discussed.
