The survey was carried out at night in the summers of 2009, 20 in St Mary's churchyard and in the adjacent parish cemetery on Kingsclere Road. The light is a form of bioluminescence a molecule called luciferin is oxidised to produce oxyluciferin, and as it oxidises it produces the yellow-green glow that the glow-worms are famous for.
Larvae can glow too, but with much fainter light and sometimes as pulsating light rather than as a continuous glow. Females usually display for two or three hours and if after that time they have not attracted a mate they stop glowing and retreat into the grass until the following night. Females displays seem to be triggered by falling light intensity level. Peak glowing time is June and July but can last from late May to September. Normally it is the virgin female beetle that glows and attracts males for mating. At night time they climb up grass stalks and glow while males fly around attracted to the characteristic glow.
The female adult beetles also hide in the undergrowth during the day. They are nocturnal and are most active during moist conditions. Larvae live in sheltered places under rocks and wood, or hide in undergrowth during the day. They are rarely found on "improved" agricultural land. Species accounts are coupled with historical backgrounds and literary epigraphs to engage and draw readers young and old into the world of these tiny sparklers.Glow-worms like chalky or limestone areas and prefer open grassland and hedges where snails and slugs are abundant. As an independent researcher working with numerous university teams, naturalist Lynn Frierson Faust, "The Lightning Bug Lady," has spent decades tracking the behavior and researching the habitats of these fascinating creatures.Based on her twenty-five years of fieldwork, this book is intended to increase understanding and appreciation of bioluminescent insects while igniting enthusiasm in a fun and informative way. It is written for all those who want to know more about the amazing world of lightning bugs and learn the secrets hidden in the flash patterns of the 75+ species found in the eastern and central United States and Canada.
