Batra (1997) describes the biology of this bee near an apple orchard at high elevation (~3100 m) in the Himalaya. Bees flew primarily between 10:00 and 13:00 only in bright sunshine. L. matianense were the most abundant bee on the apple blossoms, and were also observed on Prunus sp. blossoms.
The bees are solitary, but nest in large aggregations on south-facing vertical banks that formed the uphill slope of trails made by grazing yaks and other livestock. The nests were numerous, averaging 290 nests per square meter. L. matianense exploits the period in May and June when there is intense sunlight on south facing slopes to provision and develop its brood.
Nests were dug to a mean depth of 6.2 cm in loamy soil beneath tufts of grass which maintained a more stable temperature than nearby, unused patches. Batra (1997) reports the excavation of 14 nests, 11 of which had one cell and 3 of which had 2. A drawing of nest architecture is included. Batra (1997) concludes that apple growers could increase pollination by providing nesting substrate for L. matianense.
