Pronotum with pale yellow lateral spot
enclosed or surrounded by black coloration(1)
. Differs from C. polita and C. munda, both of which have pronotum with pale yellow lateral "C" or almost a complete yellow ring, but not a separate yellow "spot". C. sanguinea occurs across the southern US, from CA to FL and up the east coast to VA.(1)
Pronotum with pale yellow lateral "C" or almost a complete yellow ring(1)
, but not a separate yellow "spot" as found in C. sanguinea. Legs dark. Very similar to C. munda but separated by distribution - West coast and east in northern states to east slope of Rockies.
Pronotum similar to C. polita
. Legs light yellowish-brown. Distribution more eastern: East Coast (ME-FL) west to Great Plains.
The color of C. munda is typically a paler, more orangish-red, while C. polita is typically dark red. However, there is variation within each species, and color cannot be used for definite ID where ranges overlap. Leg color is more reliable: C. polita has black or dark brown legs, C. munda has light yellow-brown legs.
Some individuals may have dark markings due to damage to the developing pupa:
