These glowworms use a completely different bioluminescent chemistry from fireflies — their luciferin is unique in the animal kingdom, derived from xanthurenic acid.

Fleck-winged Hoverfly

A woodland hoverfly with white crescent markings on a dark abdomen. It is one of the earliest hoverflies to appear in spring.

💡
