Cold north-easterlies ensured that the start of May was atrocious, with virtually no moths on some nights, though a migrant Silver-y on the 7th was the earliest ever at the Bay. A slight but perceptible change to warmer weather took place on the 13th when an early Small Seraphim was found in St.George's bushes and Nemophora degeerella and Crambus lathoniellus were recorded for the first time this year. The 14th brought the first Cinnabar and after a Yellow Belle was seen on the 15th an overnight trapping session pulled in new species in the shape of Dark Swordgrass, Rustic Shoulder-knot, Poplar Hawk-moth, White-point and the first Least Black Arches to have been trapped at the Bay since 2004 . Daylight on the 16th brought a huge emergence of ca.600 Adela reaumurella in the Elms (photo on right by Ian Hodgson) and new species on the 17th included Knot Grass and Light Brocade; a species unrecorded last year. Although numbers remained fairly low, White Ermine, Heart Dart, Nutmeg and Pale-shouldered Brocade were added to the rapidly-expanding list of new species for the year on the 18th and the excellent Mother Shipton was added during daylight the next day.

A significant improvement took place on the night of the 19th, when 142 moths were trapped, including 11 new species for the year - Peppered Moth, Blood-vein, Buff-tip, Bright-line Brown-eye, Common Swift, Spectacle, Dog's Tooth, Mottled Pug, Broad-barred White, Shears and Vine's Rustic. Trapping the following night produced nearly 200 moths, including Green Carpet, Bird's Wing, Peacock, Chinese Character, Lesser Treble Bar, Setaceous Hebrew Charcter and an excellent Puss Moth, with a Sallow Kitten for company. Both Privet and Eyed Hawk-moths, Marbled Monor and the infrequently-recorded Chamomile Shark were trapped on the 21st, while Adela rufimitrella was found during daytime in the Cellars.
