poinciana longicorn!!!!!!

absolutely gorgeous huge guy who gave me a mighty and respectable bite! (below the cut due to. blood [not much]). the bite was entirely provoked and my fault due to me picking it up to relocate it with full knowledge they can give a powerful bite

what a guy!!!!!!!!

#2427 - Hybolasius crista

One of 9,776 species of insects first described by Johan Christian Fabricius, back in 1775. Another New Zealand endemic longicorn.

There are 19 species of Hybolasius in New Zealand, and others elsewhere. H. crista breeds in the stems of large-leaved Coprosma species, apparently, but little is known about their biology.

Mangorei, Taranaki, New Zealand.

To help make wood more palatable, some wood-feeding insects are assisted by symbiotic microorganisms that break down the components of wood into an edible form.

A group from Nagoya University in Japan has isolated a symbiotic yeast from adults, larvae and eggs of the Japanese longicorn beetle and identified specialized organs that store the yeast, allowing the beetles to break down the unpalatable components of wood. Their findings were published in PLOS ONE.

"I have been fascinated with longicorn beetles since childhood because there are more than 900 species in Japan and they just look cool," said Dr. Wataru Toki, a lecturer at Nagoya University. "When I visited forests as a boy, I wanted to see new longicorn beetles that I had never seen before. As a researcher, I am interested in how they eat wood, because after all humans cannot eat wood. I found several studies that suggested microorganisms could be the key."

Wood is an important part of the life cycle of the longicorn beetle. After visiting flowers to collect pollen, the female Japanese flower longicorn beetle lays eggs on dead and rotting wood. Within a month, the larvae hatch and burrow into the wood. They feed and pupate before hatching into adults. Understanding how the larvae survive by eating wood is important because they help decompose dead wood, contributing to the cycling of nutrients in the forest.

My favorite bug from home! Whitespotted sawyer. I love them, they are everywhere here in the north. If you go deep enough in the taïga, you can hear them chew through bark.
