Status:

Laphria thoracica is one of the most common species of Laphria in this region. L. thoracica is quite widespread in deciduous forests, and can often be located haunting sunlit vegetation and edge habitats from mid-May to August. Territorial males wait for females on low plants near large rotting hardwood logs on the forest floor. The abdomen color varies from completely black to fully-banded with yellow on the base of the abdomen, with many intermediates between the two extremes. The different forms are likely mimetic of different species of Bombus, and the prevalence of a given form seems to vary regionally. This is one of the best bee mimics in the genus.

There are 14 records in the project database.
