Abstract

In this note, we report the first Minnesota state records of Osmia (Helicosmia) georgica Cresson 1878,Megachile (Sayapis) inimica Cresson 1872, and Megachile (Sayapis) frugalis Cresson 1872, which were collected in 2018. We also provide the first description of the nest structure of M. frugalis. All three species typically have more southern distributions. The nest of M. frugalis shows similar structure to other species in the subgenus Sayapis Titus, such as M. inimica and M. pugnata, particularly in that the longitudinal nest cell walls lack a lining of leaf pieces, and the cell partitions are made from a layer of leaf pieces followed by a layer of masticated vegetation and soil particles.
