Glowworm or glow-worm is the common name for various groups of insect larvae and adult larviform females that glow through bioluminescence.They include the European common glow-worm and other members of the Lampyridae, but bioluminescence also occurs in the families Elateridae, Phengodidae and Rhagophthalmidae among beetles; as well as members of the genera Arachnocampa, Keroplatus and Orfelia ...
In environments where glow-worms are densely populated, cannibalism can also occur, as they may consume one another when resources are scarce. [33] The pupae can last as a food source for the larva for many days. Additionally, many adult glowworms get ensnared in the larval silk threads which are primarily designed for capturing prey. [32]
Glow worms in the Waitomo Caves. The Waitomo Glowworm Caves attraction is a cave at Waitomo on the North Island of New Zealand. It is known for its population of Arachnocampa luminosa, a glowworm species found exclusively in New Zealand. This cave is part of the waitomo streamway system that includes the Ruakuri Cave, Lucky Strike, and Tumutumu ...
The researchers found these mysterious 'glow worms' that are believed to be in their larval stage and part of a beetle species, though the exact species is unknown. Researches say they are predatory.
Glow worms are a rare sight in the UK but one young conservationist is trying to bring them back.
[33] [34] [35] In the Americas, "glow worms" are the closely related Coleopteran family Phengodidae, while in New Zealand and Australia, a "glow worm" is a luminescent larva of the fungus gnat Arachnocampa, within the true flies, Diptera. [33]
Lampyris noctiluca, [2] the common glow-worm of Europe (see also "glowworm"), is the type species of beetle in the genus Lampyris and the family Lampyridae. Lampyris noctiluca presents a conspicuous sexual dimorphism .
This family is distinct from the fireflies (family Lampyridae), which may also be called "glow-worms" in its larval stage. Some early studies suggested that Phengodidae might possibly include (or be sister taxon to) the long-lipped beetles, [ 3 ] which were formerly treated as a family Telegeusidae, but these are now treated as a subfamily ...
