R. sacraria and emergence of C. perspectalis in Denham

 Not much evidence of migrants in Denham until one R. sacraria sitting on bench by MV trap this morning! On train so no photo attached.

But somewhat concerned to have over 40 C. pespectalis in traps 10-11 Sept., and only a few in the pheromone traps. On the whole not a major problem as larvae on our Box this year. These numbers are far in excess of any previous night. I suppose I cannot exclude a non-linear effect from the combination of the pheromones and the traps!
