The forewing of the leek moth (Acrolepiopsis assectella) is greyish-brown with dark brown and white scales scattered across the entire wing. The white spots are more numerous at the terminal part of the wing. A striking feature is the bright white triangular spot near the inner edge, halfway down the wing. This white spot sometimes contains a thin brown line or a few brown scales. Occasionally, a small white spot is visible at the base of the wing and one or two small white spots at the tornus. The flight period spans two generations throughout the year, but is most prevalent in the summer and autumn. The wingspan is approximately 12 mm. Host plant: onion, leek, garlic. Dutch name: Preimot.
