Mosquitoes in Ireland?

We were in County Mayo over the last few days (more about this later), and I got bitten by mosquitoes! How do I know? Because my body over-reacts to all bites and I now have bumps on my neck, my arms and my right ear (yes, that's very itchy!). It might be midges, but I thought that midges don't bite. In my 23 years in Ireland, I've never been bitten. A sign of climate change? What next? Snakes?
