Its wingspan is 33-38 mm. The forewings are yellow marked with brown fascia and apical streak with brown chequering on the fringe. The hindwings are plain cream but are rarely seen as the species usually rests in a very distinctive and characteristic way with the forewings held out at 90° to the body with the hindwings hidden behind them. Some other members of the genus such as Northern Spinach and Barred Straw rest in a similar way. The species flies at night from June to August and is attracted to light.
The larva is green with white lines and feeds exclusively on currant. The species overwinters as an egg.
The flight season refers to the British Isles. This may vary in other parts of the range.
