This species is arboreal, typically residing in tree canopies. It will sometimes be found lower. This species is closely associated with conifer trees.
North to Ontario and British Columbia, south to Virginia and west to Oregon.
Aphids, especially those found on conifer trees.
The Eye-spotted Lady Beetle has been found to lay its eggs in the lower canopy of conifer trees, and can be found as early as April through October. They are most frequently observed May through July, coinciding with aphid populations in conifer trees. One study showed that the Eye-spotted Lady Beetle’s life cycle was comparatively more synchronized with the life cycle of Mindarus abietinus (Balsam Twig Aphid) than the non-native Asian Lady Beetle, and actively hunted M. abietinus.
