    True Katydid - (Pterophylla camellifolia)

    Bright green True Katydids are more often heard than seen thanks to their extremely loud and raucous warning call.

    Staff Writer (9/17/2015): True Katydids, or Northern Katydids, are great leaf mimics. The veins on their oval-shaped green wings helps camouflage them on virtually any tree in the forest. When standing still, they are easily looked over as part of a branch or twig. Males have a brown patch in the shape of a triangle near the head. This so-called 'saddle' resembles the dried out parts of leaves or stems so the insect's camouflage is still in tact. Females have a curved ovipositor that looks like a thick scimitar (sword).

    Though they have wings, this species does not use them much. They are fond of gliding and walking. Males have a loud screeching call that is usually heard at dusk in the summer. This call is used to attract females, who often respond with their own call, which sounds like scraping. Females lay fertilized eggs in tree bark or inside stems or twigs. Adults and larvae eat leaves.

    BUGFINDER: What Kind of Bug is This...
    BUGFINDER allows for a quick search of the Insect Identification database by selecting primary color, secondary color, number of legs and the territory / state in question. If only one color is present on your insect, select it again as its SECONDARY color. Remember that the more details you can offer, the better your chances of finding a match. As a rule of thumb, six legs are typical for most insects whereas spiders generally have eight legs.
