In reply to HC~F: My mate mik, got biten last week at work and all his arm swelld up, sent him to hospital it was that huge! then same thing happend again today only round his knee cap's looked like he had two footballs on his legs.
Just presuming there midges and not some foriegn fly's come over in the shipping containers from trusty old taiwan chiana and japan, which is a possibility.
The scottish one's (small, black with white stripes) dont give me a reaction. but the huge welsh one's, although they dont bite as much by half, god they itch...
And peak midges in my humble slightly limited expierience are just about in the middle.
