Mayfly

Near freshwater sources like lakes, rivers, and streams; nymphs are aquatic while adults are terrestrial/aerial.

Nymphs eat algae, detritus, and organic matter; adults have non-functional mouthparts and do not eat.

Known for mass emergences and short adult lifespans (minutes to days) dedicated solely to reproduction. They undergo a unique 'subimago' stage before becoming adults.

Completely harmless to humans; vital ecological role as a food source for fish and birds, and serves as a bioindicator of water quality.
