Fireflies, known as lightning bugs in the South and Midwest, are neither flies nor bugs. Scientists save the word “bug” for a specific kind of insect with sucking mouthparts—a definition that...

2005年9月5日 · Fireflies produce a chemical reaction inside their bodies that allows them to light up. This type of light production is called bioluminescence. The method by which fireflies produce light is...

2024年3月7日 · More than 2,000 firefly species are known to science, each with its own unique pattern of light flashes and differently shaped light organs. But have you ever wondered how these luminous...

2024年5月27日 · Fireflies' ability to produce their own light is called bioluminescence, which is found in select animals, bacteria and fungi all over the world. Most of these creatures live in...

Firefly luciferase genes have been isolated from more than 30 species, producing light ranging in color from green to orange-yellow. Here, we reconstructed seven ancestral firefly luciferase genes, characterized the enzymatic properties of the recombinant proteins, and determined the crystal structures of the gene from ancestral Lampyridae.

2021年6月17日 · Fireflies’ trademark flashing light is a well-known example of bioluminescence. It is generated through a chemical reaction in special organs in their abdomens. Chemicals, enzymes, oxygen and energy-transporting molecules within cells all coalesce to create light.

2024年1月19日 · Fireflies are a fascinating family of bioluminescent beetles with diverse lifestyles and behaviors. This review summarizes new findings on their taxonomic and ecological diversity, then describes recent global efforts to identify and protect the most threatened firefly species.

2001年6月29日 · We report that light production by fireflies can be stimulated by nitric oxide (NO) gas in the presence of oxygen and that NO scavengers block bioluminescence induced by the neurotransmitter octopamine. NO synthase is robustly expressed in the firefly lantern in cells interposed between nerve endings and the light-producing photocytes.

Firefly larvae have a unique combination of characters among beetles (Figs. 1–2). These larvae tend to have hardened sclerites—regionalized plates of the exoskeleton—on the dorsum (i.e., terga), venter (i.e., sterna) and sides (i.e., pleurites), which contrast with the more lightly sclerotized body of the adults.
