text: # Udea fulvalis
  
  Udea fulvalis is a species of moth of the family Crambidae. It was first described by Jacob Hübner in 1809.
  
  ## Etymology
  
  The species name fulvalis derives from the Latin fulvus, meaning fulvous.
  
  ## Distribution
  
  This species can be found in most of Europe.
  
  ## Description
  
  Udea fulvalis has a wingspan measuring between 24 and 29 mm. The uppersides of the forewings of these moths show a fulvous brown or yellowish-brown colouration, with darker markings. 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.
  
  The larvae mainly feed on a variety of plants of the family Lamiaceae (Ballota, Nepeta and Salvia pratensis, etc.), but also on Cornus and Lychnis. They pupate in a cocoon amongst leaves of the host plants.
