It was much cooler today so I ventured out to do some silk dyeing. As I was putting my hand in the passionfruit vine to find the water tank tap, I remember some advice I read lately - don't put your hand where you can't see your fingertips. As I couldn't see them, I looked more carefully. At first I was taken aback by the many little creatures I could see - but it turned out they were only harmless - to humans. But there were A LOT of them. I was not sure what they were so have done some brief research. This link has what looks like them - they are called Passion-vine Hoppers, a bit of a clue that I could be on the right track seeing they were on the passionfruit vine and they flew away when I moved the vine.
