A key to Calligrapha species of Atlantic Canada
a simplified key adapted by C.G. Majka from(1)
NB: Use the key with utmost caution beyond the indicated area, since adjacent areas (e.g. QC, ON, NY...) have much richer Calligrapha faunas

Lady Beetle Keys - University of Minnesota
Keys to adults, pupae, and larvae of seven common lady beetle species. There are very few resources, in print or online, with larval keys, and I've never seen a pupal key before. Though limited in scope, it can be used to ID the most commonly-encountered species at all life stages.

Species list:
Adalia bipunctata, two-spotted lady beetle
Coleomegilla maculata, (pink) spotted lady beetle
Coccinella septempunctata, seven-spotted lady beetle
Cycloneda munda, polished lady beetle
Harmonia axyridis, multicolored Asian lady beetle
Hippodamia convergens, convergent lady beetle
