Latest update - March 19th

Based on the current number of Glow Worm larvae recorded so far this March, 2017 looks set to be another early year for Glow Worms. Previous early years came in 2011 and 2014, when the first female Glow Worms were to appear on dates either side of the middle of May.

But the number of larvae recorded in both those years was lower than this year's current total of 14 larvae reached by March 19th.

Yet again, we failed to have any real Winter weather in Nottinghamshire, with very few frosts and only some sleety rain over the course of a single February weekend. We've thankfully not had a repeat of the drawn out, cold, cloudy Spring of last year and a series of mild days and nights early in March have certainly helped kick-start our larval surveyng season earlier.

Relatively large larval sizes also indicate an early glowing season, based on a direct comparison with the average larval size data we recorded in 2011 and 2014.

2017 Glow Worm sightings (Clipstone Old Quarter only)
Our continuous coverage of the Clipstone Old Quarter colony will hopefully resume later this Spring, surveying the same smaller area of last year. Sightings and records away from Clipstone Old Quarter, will be made available via the Nottinghamshire Glow Worm Survey page.
                 
Glow Worms (both adults and larvae) are recorded as follows.....L = larva ..... M = male .....F = female

Final update on the 2016 season

Covering a smaller survey area than in previous years, the 2016 Glow Worm season finally ended after the failure of Female 411 to appear on the evening of July 24th. Once again, we had two clear peaks in Glow Worm numbers this season, with 44 females recorded on June 19th, then a second (main) peak of 92 females on July 4th and 94 females on July 6th.
