What is the primary reason the ashy mining bee is often mistakenly perceived as rare by casual observers?

Answer

Its flight season is very short, typically active only from spring through early summer.

The perception of rarity largely stems from its highly specialized and brief activity window, usually spanning from March until early June, after which the adults disappear for the year.
