Beetles put down to wet, moon
A COMBINATION of wet weather and the full moon may have contributed to a swarm of water beetles.
Tweed Shire Council entomologist Clive Easton said the council had received several inquiries about the beetles in the Tweed last week.
“I have never seen these beetles in the numbers that were flying around Wednesday night,” Mr Easton said. “I have to put it down to seasonal conditions and a mass emergence from ponds just following the full moon.
“Water beetles often take to the wing en masse in late summer around full moon and probably use the reflected moonlight to find water pools.”
Mr Easton said La Nina had caused the wet season to begin months earlier than usual this season. “This led to large build-ups of aquatic insects in fresh water wetlands and I suspect the swarming water beetles have capitalised on this with an extended breeding season.”
