There is an article in the Sunday Herald Sun today 13/01/13 that talks about these being in plague proportions this year and says that the adults DO eat pollen and nectar. That might explain why I'm having such a lean year this year; nearly mid summer and I haven't had a harvest yet. Another bloke I know with hives a couple of K's away says it's the worst year he can remember around here.
were bad around here too they tend to clump up on the ground and on branches i made up some pyrethum spray and killed thousands, think there were some small amount of bee casualty's but not many i was careful not to spray the bees if i could help it, the bugs drop immediately so i was able to hose down the branches and get rid of residue quickly. its just a small drop in the ocean but i think it helped a bit around here theres not so many now.
