The thing about a dragonfly is that you usually see it before you hear it. Then it banks past the camera and you catch that thin papery hum that wasps and bees do not make. Wildlife editors keep a dragonfly pass on hand specifically for that hover-and-dart movement that other insect SFX cannot sell.
44 dragonfly clip is gathered here, from close wing buzz loops to short fly-bys and the slower hover that holds over still ponds. Nature b-roll, garden ASMR cuts, and fantasy scenes with oversized insects all benefit from one of these on a low track. Free to grab as MP3, no licence chase, no attribution required.
