The nests are generally constructed within large burrows in wood, cavities in old walls and also occasionally in soil. Megachile species construct nests from cut pieces of green leaf. Megachile centuncularis uses 6-14 circular leaf pieces per cell body with 6-7 discs forming the lid to each cell. Ash, birch, honeysuckle, horse-chestnut, lilac and rose leaves are utilised.
Like many other Megachile this species is often found at bramble and thistle flowers.
Coelioxys inermis (Kirby) is known to be a cleptoparasite of this species of leaf-cutter bee.
