when i said crane fly,i meant ormosia larvae(im not sure if we get them in the uk,but description and photo look the same)not tipulidae,know as leather jackets in the uk- i find them all the time in lawns and turf.what will these worms do? I thought i had 3 weeks left of flower but now could be 2,maybe just even flush for the next week as they`re looking ready any way.Roll on snow white.... thanks for the help.Peace,RM.
