A recent arrival in Belgium (2017). A very rare and local species.
Distribution based on specimens examined for genitals.
Caution is required because individuals from Aethes bilbaensis, A. flagellana, A. beatricella, A. francillana, A. tornella and A. dilucidana can only be distinguished reliably with a genital examination.
Approx Length (c. 7.5mm) Wingspan 10–15 mm. The leading edge of the forewing has a fairly broad zone with brown scales and is a relatively consistent characteristic view.
The larva lives freely on the faded umbels, feeding on the fruits of the food plant. Then it bores itself into a stem, in anticipation of hibernation where it also pupates. The adults fly mainly during the day and at dusk and comes sparsely to light.
The adults fly from late June towards September with a peak in July.
The larva lives on different species of Umbelliferae.
