Research significance

Lasioglossum , including L. pacificum, are frequently captured in large numbers in bowl (pan trap) surveys used for bee monitoring. Research has shown that bowl traps often collect disproportionate numbers of halictid species compared to the bee actually visiting flowers, potentially skewing diversity assessments.
