Here's another little quiz to get you thinking before tonight's show.
UPDATE: Sorry - we just had to drop this from Springwatch tonight. We had too much and and something had to go.
But we'll keep it here online and bring you the answer at 8pm.
Which is the odd one out and why?
We'll post the answer here on the blog after the show.
And here's your answer:
A. is a Eye Hawk Moth (thanks to Lee Summersby)
B. is Banded Snail eye (thanks to Dr Stephen Murray)
C. is Crab eye (thanks to Spencer Burrows)
So the link is they are all eyes, but A is the odd one out as it's not a real eye, only in name.
