Beetle (Longhorn timber beetle)) Calliprason pallidus
Species: C. pallidus
Scientific name: Calliprason pallidus
Synonym: Stenopotes pallidus
Common name: Longhorn timber beetle.
Calliprason pallidus is a native longhorn beetle which occurs throughout New Zealand. The adults are usually seen during December to February. The larvae attack a wide range of dead and dying native and exotic softwoods. This insect is very common in the suppressed branches of Pseudotsuga menziesii (Douglas fir) and Pinus radiata (radiata pine).
The adult beetle is >18 mm long and only >3 mm wide. The antennae are about the same length as the body. When the beetle is disturbed it emits a carbolic odour.
Mating occurs at night on tree trunks and the eggs are laid under the edges the bark. The eggs hatch in 15-26 days.
The hatched larvae bore 30 mm into the phloem-cambium region. A mature larva can attain a length of up to 20 mm and are up to 5 mm wide. When ready to pupate they bore deeper into the wood. The development from egg to adult takes at least 14 months.Since the larvae penetrate the to a depth of only 20-30 mm is not considered to be of economic importance as damage is removed in the sawmill when the first slab is removed. It cannot be present in export logs.
