Things That Glow In The Dark (Lampyris noctiluca)


A poor photo taken at night of a Glow worm in our front 'heap'
Last year we discovered a glow worm bug strolling across our path. Actually, I am relatively unsure that an insect can be said to 'stroll'; it does imply a certain nonchalance that may be well beyond the capability of such a simple life form. In fact, upon further consideration I would have thought that, if anything, its perambulations would err on the side of speed to ensure its safe passage across, what to it, must appear to be acres of no cover whatsoever.

I digress; we discovered the insect hastily making its way across the path and were intrigued, on looking in the Bug Book, as we had no idea that Glow Worms existed in the UK. Then late one evening, my wife spotted a pair in the dusk, glowing greenly in the grass of our lawn.

This year they are back and are inhabiting our pile of chipped pine from the removal of four trees from the front of our cottage. This heap is incredibly hot within and must provide a warm environment for them to wave their burnished bottoms in the air. These bright lights are the female of the species and as may be expected, the waiving of posterior pilot lights is to attract the flying males with which to mate. We now have three burning beauties in our love pile and will keep a close eye on them, especially during the rain.

Naturally, the spreading of pine chips will be delayed to encourage the gathering of Glow Worms.
