Calvia quatuordecimguttata (Linnaeus)
Orig. Comb: Coccinella 14-guttata Linnaeus, 1758
Explanation of Names
From Latin quattuordecim- "14" + guttata- "spotted"
"Cream-spotted Lady Beetle" is in wide use, but describes only the Eurasian form (where the name was coined), as well as this American form:
Length 4.0 to 5.5 mm, width 3.2 to 4.5 mm (2)
Adult: It comes in great variety of color forms. These are the major pattern variations, starting with the cream-spotted form:

Regardless of pattern, the pronotum is always shiny, and the underside is mostly black with a reddish border around the abdominal segments. The Eurasian form is chestnut-brown with 14 cream-white spots, and may occur as an adventive.

Larva: Black and white with large conical "spines" on every abdominal segment.
Map - Holarctic. In N. Amer., from n. CA to NJ north (2)
Psyllids, aphids, and other soft-bodied insects.

Second row of spots has one large spot on each side, not two spots like pink form of Calvia; at rear of body, one small spot on each side, not one large spot joined across the middle.

Larva of Propylea quatuordecimpunctata, Fourteen-spotted Lady Beetle - similar in color and pattern, but does not have pointed spines.
