Morphological anomalies of endangered Korean relict long-horned beetle Callipogon relictus (Cerambycidae, Coleoptera) during ontogenesis and possible causes of their occurrence

Abstract

This paper describes for the first time cases of exogenous morphological anomalies that occur during rearing of Callipogon relictus Semenov, 1899 in a laboratory setting. The highest frequency of the anomalies has been observed during pupation. It can be assumed that in beetles of this group, at final stages of ontogenesis, some abiotic factors such as humidity and temperature play an important role.
