I haven't done a lot of trapping in the past two months, due mainly to the extremely low night time temperatures. Agonopterix heracliana was attracted to a lit window on 9th Feb and then two days later a slight upturn in night time temps tempted me to try the traps, the first time they'd been out for almost two weeks.
The catch was from two traps at either end of the garden. It was interesting that the Twin 15w Actinic easily out performed the far larger and slightly more powerful Twin 20w Synergetic. Though this could simply be down to location. Tonight, I will be trapping again and have reversed the traps to see if it makes any difference. I have also heard that Synergetic tubes lose some of their potency after around a year's use? It would be hard for me to prove, so having had the current tubes from June 2013- I may invest in new ones for the upcoming months.
