A friend of mine in horsley was doing her gardening and whilst turning some soil came across somthing that looks just like the larva in Steve's picture, but i wasnt totally convinced as it lacked the light coloured tips that are present in the above pictures, are the light tips ever-present or do they appear at a certain stage or perhaps different genders?

I counted 5 adult females at a site West of Winchester last July.

The light organs are even present within the egg - the developing larva glows - according to John Tylers excellent book - I think there is a link to this on another thread.

What I would like to do is collate all the records from reptile recorders - dates, times, location name, etc so that we can pass this onto the glowworm recorder -

I have had some success in finding new grid squares for the species and I am also planning to take biometric data (sounds important dosent it) from two other populations in Surrey and Kent - As I am translocating reptiles in these sites where glowworms occur - the glowworms will also be relocated when they are found to the adjacent habitats - railway. ex allotment chalk downland etc

Jon,

How do you want to do this? I'm happy to note sightings as I survey.

Are you offering to be collator? and what info would you like? and how to send it?

I would assume you'd want usual grid reference, date, (time) & context (e.g. under tin!)? is met. data of use? maybe thru a PM or email?

 Hi Steve

I would be gladly be a collator for glowworm sightings - I would say that all the usual sighting data would be useful - grid reference, dates - under felt/tin or other - in the open even, met data would also be useful aswell as type of habitat - heathland, grassland, woodland etc

PM or email would be fine - any historical sightings over the last five years or so would also be welcome - I will pass info onto Rob the glowworm recorder.

Regards

JC

I have seen the glowing eggs in clumps of heathland grass. Much paler glow than the glowing females.

I often spot them under refugia and it is no problem to make a note of them on a reptile recording sheet. I've got a couple of records from Kent I'll dig out for you Jon.

Try again - I have made some room - all records of glowworms are welcome - especially if they are found under ACO's or tins etc

if anyone is interested there is a measurement which people can make - width of the pronotum -

The width of the first scale on top of the head is a good way of aging a larva - so if anyone fancies sending some data on this that would be great.
