Bug Magic ‍

Fireflies (ホタル, Hotaru, lit. Luminescent Bug)  are a family of insects in the beetle order Coleoptera. They are winged beetles, and commonly called lightning "bugs" for their conspicuous use of bioluminescence during twilight to attract mates or prey. Fireflies produce a "cold light", with no infrared or ultraviolet frequencies. This chemically produced light from the lower abdomen may be yellow, green, or pale red, with wavelengths from 510 to 670 nanometer. These bugs, despite their size, are much more powerful than one may think, especially in swarms. This is because of the innate ability to heat their bodies up to nearly 5,000ºF (2760 ºC), being able to give a person third-degree burns, if they were to be intimidated. This skill has attracted the attention of a certain mage, and caused them to create a magic to conjure and control these insects, in swarms of thousands.
