Streaked Lady Beetles are 6.5 to 8.0 mm in length. Streaked Lady Beetles are highly variable in appearance.
- Head: Black, either with a white patch in between the eyes or with a few white spots between the eyes.
- Pronotum: Dark brown to black, with a thick pale to white margin on either side, usually wrapping around the front of the pronotum. The dark brown to black center of the pronotum is trapezoidal in shape and may extend completely from one side of the pronotum to the other. There is a dark, comma-shaped spot on either side of the central dark patch, which may be connected to the central patch or occur as separate spots.
- Elytra: Yellowish-brown, brown, orange, or red. Elytra can be entirely without dark markings, or can have dark brown to black markings (very streaky in appearance) running down the elytra, parallel to the sides of the beetle. Streaked Lady Beetles may also have a few dark spots. The elytra and elytral markings are very streaky, per this lady beetle’s common name.
- Legs: Orangish-brown.
