}} Helcystogramma rufescens is a moth of the family Gelechiidae. It is found in most of Europe. The wingspan is 14–17 mm.[2] Adults are on wing from June to August.[3] The larvae feed on various grasses, including Brachypodium sylvaticum, Arrhenatherum elatius, Poa trivialis, Dactylis glomerata, Phalaris arundinacea, Melica nutans, Calamagrostis arundinacea and Calamagrostis epigejos. They spin grass blades and feed inside the spiral spinning, causing whitening of the grass blade tip. They change leaves several times. Larvae can be found from April to July. They are black and white striped.[4] References1. ^Fauna Europaea {{Taxonbar|from=Q2900900}}{{Helcystogramma-stub}}2. ^microlepidoptera.nl 3. ^[https://ukmoths.org.uk/show.php?bf=868 UKmoths] 4. ^ukflymines.co.uk 3 : Moths described in 1828|Helcystogramma|Moths of Europe |
