glow worms

Arachnocampa luminosa


Glow-worms make sticky silk threads which hang like fishing lines. Small flying insects are attracted to the light of a glow-worm, and get caught in the threads. The glow-worm pulls in the thread with its mouth and eats the insect. In the bush the lines are 1–2 centimetres long. In caves, where there is no wind to tangle the threads, the lines may be up to half a metre long. A large glow-worm larva may have as many as 70 lines.

I see. Interessante!

@ dotun55 the worms are on horizontal threads to the vertical drops. They are transparent so very difficult to see! No they are not the larvae of fireflies. There is a link attached to this spotting for more information on these fascinating creatures

Wonderful! Where are the larvae themselves and are they larvae of fireflies?

I took these pics with my little Canon ixus camera :) I was very lucky it was a still day as the slightest breath of wind makes them move. I've tried to take more photos recently but never had the success I had with these shots!
