Identification
Distinguished from other Mecoptera by the hanging posture—forelegs grasping substrate while body hangs vertically. Differs from true scorpionflies ( Panorpidae) by lacking the enlarged, recurved male genital segment. Separation from requires examination of wing venation, body proportions, and genitalic structures; B. strigosus is recognized by specific wing markings and body striping referenced in its .

Appearance
Elongate, slender body with long, thin legs adapted for hanging. Two pairs of membranous wings with distinct venation. Forelegs modified for grasping vegetation, while mid- and hindlegs are used for capturing prey. The 'striped ' suggests longitudinal striping on the body or wings, though specific pattern details require verification.
Distribution
North America; recorded from Vermont and presumably more broadly across the continent based on distribution patterns.
Behavior
Adopts characteristic hanging posture using forelegs to grasp vegetation, with remaining legs free for prey capture. This predatory strategy is shared across the Bittacidae.
Ecological Role
in terrestrial , likely contributing to control.

- Other Bittacus species share hanging and general ; precise identification requires detailed examination of wing patterns and genitalia.
