Campylomma verbasci
Pest description and crop damage Campylomma, or mullein bug, is Asian or European in origin. Adults are brownish-yellow and about 0.1 inch in length, very mobile and active. Nymphs are smaller, green, and also fast moving. The mature nymphs resemble aphids in some ways but are far more active. Feeding by nymphs causes dimpling and distortion of fruit although damage to pear is rare.
