I only caught one copy. on the first day of my arrival at the field practice, and no matter how much I didn't pick pines for two weeks afterwards, I didn't see any more of them

the story of catching this micro - bike beetle

we arrived for an early spring field practice. it was supposed to live in the houses left over from the abandoned cordon. on the territory of the cordon there was a jaeger's house, a bathhouse on the river bank and a fresh wooden toilet for two points/places (marked with the letters eM and Jo on the plan). while the female part was engaged in cleaning houses, the male part was preoccupied with harvesting firewood. a dry pine tree on the edge of the forest, 40-50 cm in diameter and 8 meters high, instantly attracted attention. our woodcutters did not calculate the trajectory of the fall and when the pine tree trembled, it became clear to everyone that now our comfortable WC will be covered with xxxx pine shorter. at the heart-rending screams of the loggers, all the free forces came running for a fine manual adjustment

, we rested on a pine tree and began to take it in the desired direction. at that moment, a large piece of bark fell off from the trunk and I saw IT on the exposed area! I immediately grabbed the bug! the further fate of the falling tree and its trajectory were already indifferent to me

A representative of the most sparsely distributed (2 species in the fauna of the Russian Federation) family Artematopidae. As far as I understand, they used to belong to the lobes (Dascillidae), and now they have been separated into a separate family, which has been brought closer to the nutcrackers.

The Far Eastern Macropogon pubescens Motsch is found on the territory of the Russian Federation. ( http://www.zin.ru/animalia/coleoptera/rus/macpubkm.htm ) and the East Siberian Macropogon sibiricus Motsch. I did not find any definitive keys or images on the sibiricus web, but I believe that the specimen caught in the Altai Mountains must most likely belong to this particular species. Based on the length of the antennae (on which the last segment is still broken off), I think that this is a male.

Macropogon sibiricus Motschulsky, 1845

Altai Republic, North-West shore of Srednemultinsky Lake, h = 1650 m; mowing of near-water vegetation; 20.07.2012
