A moth on the wing in midsummer, the bright-line brown-eye (Lacanobia oleracea) may not have an exactly a catchy title but it is an apt one as you will see on the fore-wings there is a bright (white in fact) line running across near the outer edge which looks like an ECG print with a couple of blips on it! Further up towards the centre of the wing is a brown colour spot or eye. So bright-line brown-eye it is then.
Flying from May until July the odd one frequently turns up in the moth trap but never in any numbers. Here in Dorset there is a second brood later in the year around September time.
It is a widespread species and quite common and it is happy to feed from almost any flowers. The larvae can be a pest if the hatch on cultivated tomatoes.
