Life history of Chauliognathus lugubris (F.) (Coleoptera: Cantharidae) in Tasmanian forests
Australian Journal of Entomology 36 (1), 37-44
Abstract: Aspects of the life history of Chauliognathus lugubris, a predator of eggs and early stage larvae of the Eucalyptus leafbeetle, Chrysophtharta bimaculata, were studied in southern Tasmania. In the laboratory (ambient temperature 15-25°C and artificial diet), the egg to adult period was about 10 months with seven larval stages. Advanced larvae (5th-7th instar) were collected in the field from soil litter during mid-winter. Adults were most common in the spring and early summer, with regular field collections suggesting adult longevity of 2-3 months. Based on the pattern of ovarian development of field-caught adults, in combination with the long larval development times, it appeared that C. lugubris has only one generation a year.
