Ultraviolet-induced Fluorescence. The immature stages of many Lepidoptera are known to fluoresce when showered with UV radiation. This thought-provoking article by Ben Greenaway provides a theory as to why the immature stages of many Lepidoptera are known to fluoresce and the evolutionary advantage of doing so.

MHD lease renewed. In case you missed it, a new 10-year lease for Magdalen Hill Down has been agreed between The Church Commissioners for England and Butterfly Conservation at Magdalen Hill Down. I'm sure this will come as a relief to those that volunteer and visit MHD, given the current financial pressures that BC is facing. It is, however, unfortunate that the BBC decided to use an image of a Mazarine Blue in their article, as hopeful as we are that this species might return! [Posted by Pete Eeles]

Pebble Prominent. When one of only three moths in the home trap is as beautiful as this Pebble Prominent, I don't mind. [Posted by Lee Hurrell]

Dukes showing well at Noar Hill. Saw Noar Hill in wonderful form today - in the sun with the Cowslips out, with at least 12 Dukes both male and female all around the pits. Many other butterflies were also flying including my first Green hairstreak, Dingy Skipper and Small Heath of the season. [Posted by Claire Hartt-Palmer]

Orange tips are showing well at Farlington Marshes. I returned to Farlington Portsmouth after a week away, to discover the Orange tips have emerged behind the motorway with plenty of their larval food plant Cuckoo-flower blossoming for them. [Posted by Claire Hartt-Palmer]

Early emergences at Butser Hill. I ventured to Butser Hill more in hope than anticipation in weak sunshine and an annoyingly cool easterly breeze. I took my usual route from the car park along the western hedge line and after twenty minutes I was photographing my first Duke of Burgundy of the year. What made this more pleasing is that they have been very scarce in this area for a couple of years following some fencing replacement. A few Grizzled and Dingy Skippers made use of some warmer sunshine and most surprising of all was an exceedingly early Small Heath - my earliest ever by more than two weeks! [Posted by Mark Tutton]

Morn Hill Moths. The milder night forecast for 12th April led to the moth traps being put at Morn Hill, which were checked on the 13th. A splendid 76 moths of 22 species were recorded, including the stunning Chinese Character, Lunar Marbled Brown, and Iron Prominent pictured. [Posted by Lee Hurrell]

Basing Wood Speckled Woods and Commas. A delightful couple of hours exploring Basing Wood this afternoon. Speckled Wood is emerging nicely, with six seen. Six seemed to be the magic number, as six of each of Comma, Peacock, and Green-veined White also seen. Otherwise, male Orange-tip, male Holly Blue, male Large White, male Brimstone, and both male and female Small White also seen. [Posted by Lee Hurrell]

Hampage Wood & Itchen Abbas. A walk to Hampage Wood and back this morning, primarily to track down a singing Woodlark, yielded Peacock, Small Tortoiseshell, Orange-tip and Speckled Wood. (Woodlark still singing, but remained elusive). An afternoon in the garden was enlivened by visits from Brimstone, Green-veined White, Large White, Orange-tip, Holly Blue, Peacock and, most bizarrely, a mint-fresh Green Hairstreak, which perched briefly on a window pane before shooting off as I went for the camera.

Portsdown Hill. 6th April 2025 Portsdown Hill The warm weather continues, and the butterfly numbers are getting better as the days go by. I decided to conduct a walk around my old transect route which I haven’t conducted now for several years, and I surprised how it still looks how I remember it, all be it a few more Gorse bushes which seem to be spreading. The slopes were covered with Brimstones of both sexes, along with excellent counts of Speckled Wood, and the Orange Tip has certainly responded to the warm weather. I didn’t manage the Green Hairstreak, and I was surprised that the Holly Blue didn’t appear either, with no Small Tortoiseshell either, with just a splattering of Peacocks. Cowslips here look in better condition than at Noar Hill now. The birds of prey were also absent, but I suspect most of them are concentrating on nest building and looking after young.

Small tortoiseshells in decent numbers at St Clair’s Meadow Soberton. I walked the transect at St Clair’s Meadow Soberton this morning for Hampshire and Isle of Wight Wildlife Trust. It was sunny but quite windy, and the wind had a chill to it. I saw 6 Small Tortoiseshells and 5 Peacocks. They were all appearing out of the grass and undergrowth as it warmed up. There were a few distant whites across the other side of the river, but no Orange tips were seen. The cuckoo flower is out so hopefully they will be around shortly. It is still quite wet and muddy in places- wellies are still a good idea! [Posted by Claire Hartt-Palmer]

Visit to Noar Hill. I visited Noar Hill today from around 11.30 to 14.30. Although it was pleasantly warm in the chalk pits, which were sheltered from the breeze, it was half an hour before I saw my first butterfly - a female Brimstone. There is a good spread of violets and the cowslips are coming into flower. During my visit I saw: Brimstone: 12+ Peacock: 6+ Comma: 1 Holly Blue: 1 Orange-tip: 1 Speckled Wood: 1 And half-a-dozen whites (unidentified) [Posted by Kevin Freeborn]
