"Portrayed here is a male Common Garden Katydid (Caedicia simplex) removing pollen or other substance from the end of its abdomen after obtaining it from the petal of a camellia flower. While I was observing it, a Common Green Mantid nymph (Orthodera ministralis) peered up from behind the flower petal, curiously watching me and its intriguing katydid companion." Image: Paul Farley
