Bioluminescence in the adhesive web of predatory larvae of fungus gnats
Summary[edit]
| Description |
English: Bioluminescence in a limestone karst cavity in Dorrigo National Park, New South Wales, Australia. Larvae of the fungus gnat Arachnocampa richardsae, unique to eastern Australia, produce adhesive liquid droplets forming "necklaces" hanging down from the rock. The luminosity results from a chemical reaction involving the heterocyclic substance luciferin, taking place in altered secretion organs known as Malpighian tubules. The emitted light serves to attract insects, which become ensnared by the sticky droplets, providing a food source for gnats.
The pink glow in the photo is caused by lichens, illuminated by an ultraviolet flashlight.
Українська: Біолюмінесценція у карстовій порожнині вапнякової скелі в Національному парку Дорріго, Новий Південний Уельс, Австралія. Краплі клейкої рідини, з’єднані у своєрідні «намиста», виділяють личинки грибних комарів Arachnocampa richardsae, ендеми східної Австралії. Світіння є результатом хімічної реакції окислення гетероциклічної сполуки − люциферину. Ця реакція відбувається у видозмінених органах виділення личинки, мальпігієвих судинах. Світло приваблює комах, які прилипають до клейких крапель і стають їжею комариків. Рожеве сяйво на світлині спричиняють лишайники, підсвічені ультрафіолетовим ліхтариком.
