LEPIDOPTERA
Painted Ladies were quite common around Aldeburgh and Thorpeness after this, and Red Admirals (Vanessa atalanta, L.) also. On August 17th, I pursued a Clouded Yellow (Colias croceus, Fourcroy) across East Bridge marshes, tili it crossed the Minsmere river, and another was seen at Aldeburgh that day. At Sotterley, on the same day, while watching a Purple Hairstreak (Thecla quercus, L.) on a tree branch, I saw a Comma (Polygonia c-album, L.) which, though not so common in the last few years, still stays with us. I did not search for White Admirals (Limenitis Camilla, L.) or High Brown Fritillaries (Argynnis cydippe, L.) this year at Blythburgh, but am told that one White Admiral was seen there, but no Fritillaries, a repetition of my experience there in 1957. In 1956, I saw male Fritillaries only ; let us hope the colony survives.

THE early months of 1958 were on the whole average for the winter period, with the result that most of the lepidoptera were on the wing at their normal dates. T h e first butterflies of the year, the Small White (Pieris rapae Linn.) and the Orange-tip (Anthocharis cardamines Linn.) were fully out by the middle of April, but a cool spell in early May prevented the appearance of the Pearl-bordered Fritillary (Clossiana euphrosyne Linn.) tili well into the latter half of that month. DĂźring the first fortnight, of May, however, there was quite an immigration of the Bordered Straw (Heliothis peltigera Schiff.) along the south coast which also was the scene of several records of the Striped Hawkmoth (Celerio livornica, Esp.) some of which penetrated to the Home Counties Quite a number of the Painted Lady (Pyrameis cardui Linn.) also appeared in the South about this time.
