@JonLewis Jon, I think you are right. I hope this doesn't mean I have termites. Just looking at some photos from about 12 months ago, not yet posted, and I had hundreds of these attracted to a UV light one night.
@AlisonMilton. We get similar events at our place - you just need a nest somewhere nearby and a light on your house and they turn up in droves. The bats & birds like them though.
Hi Don, I suggested Coptotermes only because CNM seemed not to allow me to choose a higher termite classification and thought someone who knew better would fix it! Cheers, Jon
