The name (both common and Latin) of the Disk-marked Lady Beetle (H. disconotata from Latin discus) refer to the oval, disk-shaped markings on the wing covers.
The Disk-marked Lady Beetle is 2.3 to 2.8 mm in length. The body is overall elongate in form.
- Head: Black. Male heads may have a pale patch, this is unclear.
- Pronotum: Female pronotum is entirely black. Male pronotum is black and may have a pale margin along the sides, wrapping across the front.
- Elytra: Black, with 5 yellow to orange spots per elytron (10 total across the wing covers). The spots are very elongated, appearing as thin ovals or disks. The basal spots (top of the wing covers, closest to the pronotum and head) on each wing cover nearly touch (see the first photo for reference). Distinct, oval shaped humeral spot (middle of wing covers near the suture where the wing covers close together).
- The whole beetle is finely punctured (appears like it was pricked with a pin many times).
- Legs are orange.
- Often confused with the Octavia Lady Beetle (Hyperaspis octavia), Undulate Sigil Lady Beetle (Hyperaspis undulata), and Ten-spotted Spurleg Lady Beetle (Brachiacantha decempustulata).
There is some indication that this species may be arboreal, also found in boreal ecosystems.
West to the upper mid-western United States, east to the New England coast, and north to Quebec through Alberta.
Likely aphids or scale insects.
