Etymology

The species name fulvalis derives from the Latin fulvus, meaning fulvous.

Distribution

This species can be found in most of Europe. [1]

Description

Udea fulvalis has a wingspan measuring between 24 and 29 mm. [2] The uppersides of the forewings of these moths show a fulvous brown or yellowish-brown colouration, with darker markings.[2] Larvae are pale green, with a black head.

Adults of this species are rather similar to Ebulea crocealis and Udea prunalis.

Biology

Adults are on wing in one generation a year (univoltine species) from June to late August, depending on location. They preferably fly at night, when they come to light. [3]

The larvae mainly feed on a variety of plants of the family Lamiaceae[2] (Ballota, Nepeta and Salvia pratensis, etc.), but also on Cornus and Lychnis. They pupate in a cocoon amongst leaves of the host plants. [3]
