A Horse-Fly female, which are the ones that bite, and this one properly known as a Notch-Horned Cleg Fly and my brother Ryan is holding the fly after just capturing it. Unfortunately the reason behind him NOTICING it was that it had just bit him in the hand!
Also seen the Latin listed on Wikipedia (cannot be trusted) as Haematopota psedolusitanica (straight away I am pretty sure the species name should be pseudolusitanica so 'pseudo' and not 'psedo')
