Doodle Science - July 2015



Circulated to schools, organisations and individuals - covering primary science and related bits and bobs.



Horse Fly

This beautiful insect is one you would not want to meet too close, it is a horse fly, if I have read my insect guides right it is Tabanus bovinus, not one that commonly bites people but mainly cattle and it is apparently quite common. One thing about these insects is they have the most lovely eyes, every colour of the rainbow, so if something lands on you and it has iridescent eyes brush it off quickly. When I first spotted it I thought it was the drone fly which is absolutely harmless, but then I saw the dagger mouth parts. Only the girls ones bite, by the way, the boys drink nectar.
