Light Pollution

Benton's picture

Insects form the basis of prey for many species including bats and birds. Broad spectrum white light or light with a high ultraviolet content can 'hoover' up to 75% of the insects from a habitat -the so-called 'vacuum effect'. Around a third of these insects will die.

Open Mosaic Habitat

Benton's picture

Greater protection exists for brownfield sites (from a very low base) with the Open Mosaic Habitat  OMH Survey Form and associated OMH Survey Handbook. This is the first time the UK has recognised brownfield as a Priority Habitat.

In order to qualify the following  5 criteria in the table need to be met. This will help recognise the importance of sites in the Thames Gateway. The photograph shows dead bramble stems on bare ground which offers oppotunities for breeding for some insect species.




Not really a blog - just a few sightings from the last couple of days. 

Had a wander around Woods Mill (Graeme and Penny's place of employment) yesterday to show mum some bluebells - and she also heard her first Nightingale :) The hoverfly Leucozona lucorum was new for me but only one (poor) photo as the damned thing wouldn't sit still! Saw some interesting spider behaviour in the vegetation by the big pond. One (terrible) photo, but the males were enthusiastically waving their palps around! Also saw my first Large Red Damsel for the year.

A single firebug at the Sompting...

Damaged Balls

Had a good relaxed couple of hours out late morning. Free from the shackles of last year's 1000 in 1kmsq, I spent most of the time in my 1kmsq ...


Nothing new for the list (at least I don't think so, but I have a couple of bits potted up to check). A few spring day-flying moths about (Adela reaumurella, Incurvaria masculella, Pammene rhediella, Elachista apicipunctella, Anthophila fabriciana) but otherwise a bit quiet apart from lots of diptera and sawflies of the varieties that I tend to ignore at the moment. Not much beetle action either, but Ischnomera cyanea nice...
