Explanation of Names
Oberea schaumii LeConte 1852
Type collected by Dr. Schaum in New Orleans, LA
Per Lingafelter (2007), first two or three abdominal sternites nearly completely dark (at least at center), remainder pale yellow or testaceous, rear top of head usually dark, posterolateral pronotal spot usually larger than the central spot. (1)

Det. M. A. Quinn, 2016
e. NA to AB - Map (1)(2)(3), less common in the south
May-July (1)
Larvae are girdlers of living branches of cottonwood (Populus, Salicaceae) (1)
Life Cycle
Eggs are laid in the stems and branches of suckers and seedlings. The larvae feed near the pith, excavating tunnels up to 6" long and boring frass expulsion holes. Black, necrotic areas develop around these holes.(4)
the descriptions of Oberea schaumii, caseyi, pruinosa in Lingafelter (2007) and Yanega (1996) are in disagreement with each other. (1)(5)
