This evening, Mark, Lumart and I were at The Knoll. Lumart has a torch which emits ultra violet light. The most striking effect is achieved on the mottled scorpion, which lights up in spectacular fashion. After recent rain, there were large numbers of scorpions around and I filmed a lone specimen which was static for a long period and then moved off. I also filmed a mating couple, pincers clasping pincers. The pair were on a root. The male pulled the female off the root, relocating just below it. I also filmed a plant shoot with just two leaves, whose venation responded to the ultra violet.
