Scottianella dalei
Family: Delphacidae

A small but striking delphacid, sometimes included under Strubingianella, but distinctly different from S. lugubrina.

The frons, vertex, pronotum and forewings of males are yellowish to pale golden brown, but the scutellum is black, sometimes yellow at the extreme apex. The abdomen is pale at the base and around the midline towards the apex, but dominantly black. Females are entirely light yellow-brown. Both sexes are normally brachypterous, although macropters may occur rarely.

A relatively scarce species on open grassland in southern counties of England.

Compare Hyledelphax elegantulus.

Adult: March to August
Length 1.7-2.5 mm
