Larval systematics of North American Cycloneda Crotch (Coleoptera: Coccinellidae)
By Robert Gordon and Natalia Vandenberg
Insect Systematics and Evolution, vol. 28, no. 3, 1993
Cite: 334286
Invaluable aid for identifying 4th-instar larvae of Cycloneda lady beetles. Key to the three North American species; detailed description, line drawings, and microscopic photos of each species; discussion on separating these three species from a related Central American Cycloneda, and of the Cycloneda genus from other lady beetle larvae.

With this key, I find it easier to identify the larvae of Cycloneda munda, C. polita, and C. sanguinea than the adults!
