The legs of this species are covered in dense whitish pile, while the scutum is sparsely-haired, and often looks bare from some angles. This species shows pale pile on abdominal segments 5-6, and black scutellar bristles.
Adults are perch hunters, flying up to capture flying insect prey.
Remarks
Laphria cinerea is found of sitting on pine trunks, or on pine logs on the ground. It is generally quite wary, and usually doesn't stay in one perch for very long.
