Abstract

The halictine bee, Lasioglossum (Evylaeus) matianense (Bltithgen) is the most abundant bee in early May, pollinating apples soon after snowmelt at Harsil, India (elevation 2600 m), and pollinating Prunus sp. at Gangotri, India (elevation 3100 m). It nests in south-facing, sunny banks, where density reaches 2403 nests per m2 (x:290 nests per m2). The nests of this probably solitary species are short, sinuous, nearly horizontal burrows, ending in 1 or 2 cells at a mean depth of 6.2 cm. This bee thermoregulates its nests by placing them in relatively cool, moist soil among grass roots near the tops of the banks.
