just had a bad experience with these hughe ass black flys that are around the leaders out from the brissie river. Normally i dont react to horse flys , sand flys etc. but i;ve just met my match.noticed them on the weekend only biting my feet, they are the size of horse fly and don;t they bite. jet black and i can't say i've seen them before. anyway just finished work and went straight to the quacks. unbelieveable itching and my right foot has swoolen like a balloon. Any one else had a run in with these blokes. Being near the port i thought it may be another introduced pest like bloody fire ants, For god sake if you've got kids out there and you see these buggers put some rid or something on the youngsters because this has been unbearable itching and i'd hate to see this happen to one of our young ones ,cheers
