description Megachile lapponica Overview

Megachile lapponica is a species of leafcutter bee found across northern Europe and northern Asia, first described by Swedish entomologist Carl Gustaf Thomson in 1872. Like other members of the genus Megachile, females construct nest cells using pieces of leaves or petals, which they cut with their mandibles and carry back to pre-existing cavities. M. lapponica exhibits a strong oligolectic relationship with fireweed (Chamerion angustifolium), from which it collects both nectar and pollen almost exclusively.

This specialization makes the bee's distribution closely tied to areas where fireweed grows, particularly in disturbed habitats and forest clearings across its range.
