Ochina ptinoides (Marsham, 1802)
    A local insect throughout England, Wales and Scotland, may be common where found. Associated with Ivy, the larvae bore into the stems. Adults are active from early may until at least august and may be found on umbel flowers during hot weather. They are also nocturnal, coming to MV or flying into illuminated rooms. Common throughout the Watford area; from several locations in Cassiobury park on umbels near ivy clad trees and at light in the town centre. During hot weather they can be found, sometimes in numbers, by holding a net beneath a dense growth of Ivy and running a stick up and down through the foliage.
    2.5-3.5mm. Antennae 11 segmented and serrate in both sexes, 1st segment curved, second globose, terminal segment long and pointed. Head black or pitchy red with prominent eyes and mandibles, finely punctate, shining and with very sparse pubescence. Pronotum characteristic; highly arched with explanate sides and sharp lateral margin, clothed with dense recumbent yellow pubescence. Elytra brown often with obscurely delimited red subapical area. Indistinctly sculptured around scutellum with humeral prominences and a distinct and deep longitudinal basolateral incision. Pubescence generally forming transverse bands before middle and apex. Legs slender and pubescent, tibiae with small spines apically on inner side. Tarsi 5-5-5 with long first segment. Claws tiny, broadly toothed at base.
