to assess the role of lepidoptera migrations

on the native fauna. The latter aspect was

assessed with use of automatic light traps

with a 250 W Halogen bulb as attracting

source. In 1990-92 three light traps of this

type were used on sites on Suðuroy, Sandoy

and on Streymoy near Tórshavn. In 1993-

95 four traps were used on Streymoy, Nóls-

oy, Sandoy and Suðuroy, besides one in

1993 on Viðoy, which in August 1994 was

moved to the isolated Stóra Dímun. In 1996

two light traps were moved from Sandoy

and Streymoy to new sites on Viðoy and

Skúvoy. In 1997 the light trap sites on

Suðuroy, Stóra Dímun and Viðoy were

closed down, but three light traps have been

in use on the northeastern isles Fugloy and

Kunoy, and on the western island Vágar.

All light traps have been operative from

May-June and onwards to November. They

have been emptied with weekly intervals

and their content sent by post to SK for de-

termination and preparation. The material

will later on be distributed between both

museums. The field studies have included

annual visits of two weeks duration, from

the middle of June to the end of August.

During these visits different habitats have

been visited on most Faroe isles, and col-

lecting work has been made, mainly during

daytime. Fig.l shows the location of the

light traps and the collecting areas visited.

During the study period from 1990 to 1997

46 lepidoptera species, previously un-

known to the Faroe Islands, have been en-

countered together with 51 earlier recog-

nized species.

The aim of the present article has been to

provide an updated checklist on the lepi-

doptera fauna of the Faroe Islands, where

the present status of the many new species

is commented.

A checklist of the Lepidoptera from The

Faroe Islands

The systematics and the nomenclature of

the following list is in accordance with the

latest European checklist (Karsholt and Ra-

zowski, 1996). For each species the follow-

ing information is given:

* a species not included in the checklist by

Wolff(1970).

- scientific name and authorship

- subspecific name and author if the

species is represented by a distinct local

race

- local status according to the following

codes: R:resident N:naturalized S:synan-

thropous M:migrant Vvagrant ( migrant

with 1-5 records) Cxasual introduction

U: unknown status.

- observed flight period by months

Species not recorded since 1989 are shown

with italics in the list. Figure numbers in

brackets after the species names refer to the

comments following the list.
