On 24 and 26 June 1992 we censused 150 Clastoptera obtusa spittles on Alnus rugosa at Lulu Lake, Wisconsin, for the presence or absence of Cladochaeta inversa larvae, then enclosed the spittles in situ with "sleeves" of fine netting to confine emerging spittlebugs.
Clastoptera obtusa nymphs and associated Cladochaeta inversa larvae were collected from Tilia americana at the Little Red School House, Illinois, site and Alnus rugosa at the Beck's Woods, Illinois, site.
obtusa specimens taken from Tilia americana and Alnus rugosa showed no differentiation between host plants).
