Letter: Warm summer glow

Sir: Professor J. R. Pole suggests (letter, 9 July) that fireflies could survive our climate. I cherish a memory of cycling home after a student party in the pub at Fordwich near Canterbury and seeing the banks of the road resplendent with fireflies. Were they really fireflies as I have believed for 56 years or was it the effect of mild beer at a shilling a pint?

Yours faithfully,

R. A. HACK
