Insect
Variable Darner
Aeshna interruptaAlso known as Interrupted Darner
Variable Darners are large, striking dragonflies recognized by the broken, spot-like blue or green stripes along their thorax. Males actively patrol marshy lake margins and peat bogs, hovering in sunny openings before darting off to chase rivals or intercept flying prey. Females oviposit into aquatic vegetation, laying eggs that produce voracious aquatic nymphs capable of hunting small fish and tadpoles.

Responsible observation
- Binocular Viewing: Use close-focus binoculars to inspect the interrupted thoracic stripes while they perch.
