Chaitophorus populifolii
Chaitophorus populifolii is a species of aphid in the family Aphididae, described by Essig in 1912. It belongs to the subfamily Chaitophorinae, a group of aphids commonly associated with woody host plants, particularly in the Salicaceae family. The species name suggests an association with poplar foliage (Populus species). Like other members of its genus, it is presumed to feed on phloem sap using piercing-sucking mouthparts. Published records for this species are limited, with few documented observations.
Megachile inermis
Unarmed Leafcutter Bee
Megachile inermis is a solitary leafcutter bee described by Provancher in 1888. Unlike many Megachile species that use pre-existing cavities, this bee excavates its own nesting tunnels in decayed poplar wood. It has been recorded from trap-nest studies in Saskatchewan, Manitoba, and Wisconsin, with a notable male-biased sex ratio in rearings.
