Females measure around 10mm, and the males around 7mm. The species is rare and currently confined to southern England. Lesser glow-worm ( Phosphaenus hemipterus) View a glow-worm 10km distribution map of Wales. Move away from artificial light such as street lamps, car headlights, and houses to see the greenish light of a glow-worm more clearly. The adults do not eat anything, and only live for 14-21 days, until the female has mated and laid eggs. The larvae live a little longer and are seen between April and October.Īdults are only around for a short period in June and July, and the larvae between April and October. The larvae are most often seen living under rocks on chalk or limestone grasslands and feeding on slugs and snails. They use sickle-shaped jaws to inject a toxin which both paralyses and liquefies their prey. Gardens, hedgerows, railway embankments, woodland rides, heathland and cliffs are all possible habitats for glow-worms. The female sits in high up on a grass stem at night emitting a steady (not flashing) yellowish-green light from the end of her abdomen. The male, larvae and eggs can also emit light, although much more weakly than the female. The light is used to attract a flying male. 20mm in length. The larvae have prominent pale yellowy-orange triangular markings at the side of each segment which are not present on the females. The female has a completely black back with a thin paler line down its centre, whilst the larvae tend to be more greyish-brown. nat.Despite their name, the glow-worm is actually a beetle, not a worm! The males look like typical beetles with wings and hard wing cases known as elytra. They are light brown in colour, have large photosensitive eyes, and measure c.15mm in length. The females look very similar to the larvae (known as larviform females), have no wings, and measure c. This live radio play was developed in co-operation with Robert Schoen (dramaturgy), David Fitzgerald (stage set), Mathias Wendelin (lighting design). At the ZKM Karlsruhe Kaegi developed for the Festival Intermedium 2002 an experiment for two hunters. Silvia and Reto build acoustic weapons out of household appliances and food, manipulate toasters, make pickles glow, breed grain weevils that can only be heard with special microphones, and send house borers out to chew up billboards within two hours.
Their role models are bombardier beetles, which excrete exploding secretions when threatened, and glow worms, which imitate the blinking frequencies of the larvae of other species in order to attract and eat them.
Silvia and Reto live underground, battling the shallowness of global ad campaigns.
