The lepidopterist Austin Richardson made annual visits to the Isles of Scilly from 1956 to 1962 recording the moths and butterflies. On 14 September 1958, during a visit to Annet, he saw a crimson speckled ("Utetheisa pulchella"); a migrant moth whose larvae have never been found in Britain. He did not see any larva of the grass eggar ("Lasiocampa trifolii") but the imago was found there the following August. K Smith visited Annet in June 1961 to record the diptera and also found a moth, the garden tiger ("Arctia caja").
