Confirmed, I had 3 of these, they're blighters. I found that they came to the front of the tank when it was completely dark.... which usually meant I ended up trying to catch them after I'd got back from the pub/cinema/theatre etc. Good luck with disposing of them :?
When a mummy dragonfly and a daddy dragonfly get together... No, I'd imagine when the plants are grown in whichever nurseries they are more than likely outdoors, so open to insects laying eggs on them.
