In 2024, at Buffalora two male H. schedli were collected together with one male of H. handschini by means of light trapping, whereas in 2023 only two male H. handschini were collected with beating.

In 2024, all H. schedli were collected using light traps, whereas in 2025, one male was collected by beating Pinus cembra .
