Abstract [sv]

Rapporten sammanfattar fjärilsinventeringar utförda inom 2016 inom Biogeografisk Uppföljning som drivs av Naturvårdsverket. I fjällområdet kunde 64 ytor inventeras och sammanlagt noterades 80 högnordiska blåvingar på 20 ytor och 55 dvärgpärlemorfjärilar på 19 ytor. Inventeringen gav dessvärre inget fynd av fjällsilversmygare detta år. Förekomsten av tajgafjällfly undersöktes på 8 lokaler från Lycksele lappmark i söder till Torne lappmark i norr, totalt noterades 19 individer på 6 av dessa lokaler. Svartfläckig blåvinge sågs med 157 individer på 30 inventerade lokaler och tillsammans med data från Svensk Dagfjärilsövervakning täcktes en stor del av artens förekomstområde. Brun gräsfjäril inventerades på 35 lokaler i Dalarna, Värmland och Västra Götaland och resulterade i totalt 552 observerade individer. Asknät- och väddnätfjäril inventeras med räkning av larvkolonier i augustiseptember. På 97 lokaler som inventerades noterades 4867 larvkolonier av väddnätfjäril. Asknätfjäril inventerades på 5 lokaler i Uppsala län, 8 områden i Örebro län samt 21 lokaler i Stockholm med totalt 870 noterade kolonier. Mnemosynefjäril inventerades på 32 lokaler i Blekinge, Stockholm, Uppsala och Västernorrlands län med totalt 585 noterade individer. Pilotförsök med inventeringar av apollofjäril genomfördes under 2016 i Kalmar och Södermanlands län med totalt 8 observerade individer på 13 lokaler. Violett guldvinge inventerades på 31 lokaler i Jämtland, Västernorrland och Västerbotten där totalt 26 individer inräknades. Under 2016 har också inventeringar av dårgräsfjäril genomförts på 10 lokaler fördelade i Östergötland och på Gotland. Totalt observerades 1407 individer varav 922 sågs på Gotland och resterande 485 i Östergötland.

This report summarizes the monitoring of butterflies and moths during 2016 within the Biogeographical Monitoring operated by Naturvårdsverket, the Swedish Environmental Protection Agency. This project includes the monitoring of eleven butterfly species and one moth species, all listed in the EU Habitats Directive. Three of the butterfly species can be found in the northernmost part of Sweden and during this year a total of 66 areas were monitored. The Arctic Blue (Agriades aquilo) was found in 20 areas with a total of 80 individuals. The Dusky-winged Fritillary, Boloria improba, was found in 19 areas with a total of 55 individuals. No individuals of Hesperia comma catena could be found this year. During 2016 the species Xestia borealis, the only Swedish noctuid moth listed in the habitat directive, was monitored in 8 areas from Lycksele lappmark to Torne lappmark. The species was found in 6 of these areas with a total of 19 individuals. Large Blue (Phengaris arion) was observed with 155 individuals in 30 areas and combined with the data from the Swedish Butterfly Monitoring Scheme the area of occupancy of this species can be considered to be well covered within its Swedish range. The Scarce Heath (Coenonympha hero) was monitored in 49 areas in Dalarna, Värmland and Västra Götaland counties with a total of 552 individuals noted. Marsh Fritillary (Euphydryas aurinia) and Scarce Fritillary (Euphydryas maturna) are both monitored by counting larval colonies during August-September. 4870 larvae colonies of the Marsh Fritillary were observed in 104 areas, and the Scarce Fritillary was monitored in 4 areas in Uppsala, 13 areas in Örebro and 23 areas in Stockholm counties with a total of 881 colonies in these counties. The Clouded Apollo (Parnassius mnemosyne) was monitored in 32 areas in Blekinge, Stockholm, Uppsala and Västernorrland counties with a total of 585 individuals. The Apollo (Parnassius apollo) was monitored as a pilot experiment in Kalmar and Södermanland counties with 8 butterflies in 18 areas. The Violet Copper (Lycaena helle) was surveyed in 24 areas in Jämtland, Västernorrland and Västerbotten counties where 26 individuals were observed. The monitoring scheme of 2016 also included a survey of the Woodland Brown (Lopinga achine), recording 922 individuals in 4 areas on Gotland and 485 individuals in 6 areas in Östergötland counties.
