The 2010 season ended when Female 490 glowed for the final time on August 11th. She was present for a record 31 evenings, only failing to glow on just one evening since first appearing back on July 11th.

The total number of females was also another record, with 502 recorded during the year.

Larvae were only counted along the lengthy section of cycle path on site. The track runs north to south and was walked it's full length twice during counting, with around an hour spent each visit. The path was re-surfaced over Winter and heavy machinery had been used. Although a protective track was laid over the grass, to try and lessen the amount of affect on invertebrates, this did compact the grass and soil adjacent to the path.

The number and size ranges of Glow Worm larvae recorded at Clipstone Old Quarter was considerably different from the corresponding period in 2009. Comparison between the two graphs produced below, show that many more smaller larvae in the 12-16mm and 17-21mm size ranges were recorded, which probably means that these will not become fully grown in 2010.

The photograph above right, shows a full grown larva we had in captivity, found in another area of Clipstone Old Quarter where no larval counts are conducted. She started the pupation process on May 6th, pupated on May 11th and hatched as an adult on May 21st. She was released on May 24th and does not feature in any of the counts made during 2010. An interesting observation we never noticed with females in the pupal stage last year, was the unhatched females ability to glow fully from about 48 hours prior to emergence, although the glowing period was only for several minutes at a time.
