At least a dozen of these gorgeous little moths were on the oregano flowers by our garden shed. I didn't notice them at first as I was looking at the more obvious bees that were buzzing around the same plants, but once I had spotted one a lot more came into focus. These little beauties fly both at night and during the day.
The mint moth (Pyrausta aurata) has a wing span of just 10-15 millimetres and feeds off mint, lemon balm, marjoram and oregano. They really are gorgeous and worth looking out for.
