Yes, it is possible that many harmless insects such as beetles and flies resemble stinging yellow jackets. The yellow jacket-like sugar maple borer (Glycobius speciosus) may be considered among the more harmless of the harmful long-horned wood-boring beetles since its impact is more defective timber -- through larval galleries and twisted grain -- than dead wood. The yellow jacket hover fly (Milesia virginiensis) serves as a pollinator whose larval stages prey upon decaying animal and plant matter and upon aphids and thrips.
