Habitat
Subalpine coniferous forests in highland regions; at least one occupies high-elevation in central Japan with seasonal vertical microdistribution patterns.
Distribution
Northern Hemisphere temperate regions: documented from Denmark, Norway, Sweden, Vermont (USA), and highlands of central Japan.
Seasonality
Seasonal activity patterns documented for Thricops diaphanus in central Japan, with vertical microdistribution changing seasonally; no seasonal altitudinal observed.
Life Cycle
Thricops diaphanus has been observed to have a (one per year) at highlands in central Japan, determined through ovarian examination of wild-caught specimens. This contrasts with multivoltine cycles reported for the same in Europe.
Behavior
No seasonal altitudinal between highlands and lowlands has been observed in studied . Seasonal modification of vertical microdistribution within subalpine forests appears related to fungi distribution.

Glacial relict hypothesis
Thricops diaphanus in central Japan has been suggested as a glacial relict based on its highland distribution and pattern.
