Earwigs : Anisolarbis littorea : Giant earwig ...only males left

(Giant seashore earwig)

Anisolabis littorea : ( A. White 1846)

Anisolabis littorea is commonly known as the Seashore earwig.
Similar both ecologically and taxonomically to the Maritime earwig, this species is commonly found on beaches under stones and debris. It is a carnivore, feeding on millipedes, flies, and Isopods. Like most other earwigs, the females care for their young during development, and the larva go through five instars before becoming adults. The species also has a negative phototaxis, meaning that it tends to move away from a light source.
witnessed my giant New Zealand earwigs feeding last night (18.9.13) for the first time, as I seldom get the time to sit and watch anything but they are quite fascinating. When they attack their prey they bend their abdomen over their head and grab the prey with the pincers almost like a scorpion. As the prey was quite large, they continually harried the cricket, constantly hitting it and grabbing it with their pincers and biting it when it was held down until after 5 minutes or so, the cricket succumbed and the earwig held it down with the pincers arched over its head. Absolutely fascinating. One of our customers has reported that one of the earwigs they bought has now had a clutch of eggs and is busy guarding them. I also now understand that you can sex the earwigs by looking at the curvature of the pincers, but I am yet to check that out on the giant New Zealand species
