Tribe Sogdini
22 spp. in 7 genera north of Mexico; ca. 12 genera worldwide(1)
1.7-6.5 mm(1)
north temperate and south temperate parts of the world; in NA, markedly boreomontane (most diverse in the n. half of the continent, along the Rockies, and in the Northwest), with just one se. sp. in so. Appalachians(1)
mostly cool temperate and moist forested or open environments; some prefer well-drained sandy soils (easier to dig for fungi)(1)
active during various seasons, often in midsummer, but some spp. are known mostly from late fall/winter months; Macrohydnobius are often taken from snow surface in montane regions(1)
where known, adults and larvae feed on subterranean fungi(1)
