The greater angle-wing katydid<\/strong> is a large green insect famous for its remarkable leaf-like wings and nighttime calls. Scientifically known as Microcentrum rhombifolium<\/em>, it lives mainly in trees and shrubs across eastern and southwestern parts of the United States. Its flattened wings, long antennae, and vivid green coloration provide excellent camouflage among foliage. Although it resembles a grasshopper, it is a true katydid. This guide covers identification, size, habitat, diet, sound, nymphs, life cycle, bite behavior, and greater versus lesser angle-wing katydids.<\/p>\n\n\n\n

What Is a Greater Angle-Wing Katydid?<\/strong><\/h2>\n\n\n\n

The greater angle-wing katydid belongs to the family Tettigoniidae and genus Microcentrum<\/em>. It gets its common name from the distinctive angular outline of its broad wings. Adults are impressive leaf mimics, with wing veins that resemble the veins of real leaves. They normally spend much of their time among trees and tall shrubs rather than on the ground.<\/p>\n\n\n\n

Greater Angle-Wing Katydid Identification<\/strong><\/h3>\n\n\n\n

Look for these characteristics:<\/p>\n\n\n\n

    \n
  • Scientific name: Microcentrum rhombifolium<\/em><\/li>\n\n\n\n
  • Family: Tettigoniidae<\/li>\n\n\n\n
  • Order: Orthoptera<\/li>\n\n\n\n
  • Bright green body<\/li>\n\n\n\n
  • Broad, leaf-shaped wings<\/li>\n\n\n\n
  • Strongly angled wing edges<\/li>\n\n\n\n
  • Intricate leaf-like wing veins<\/li>\n\n\n\n
  • Very long, threadlike antennae<\/li>\n\n\n\n
  • Powerful hind legs<\/li>\n\n\n\n
  • Body and wings approximately 52\u201363 mm long<\/li>\n\n\n\n
  • Green sound-producing area on adult males<\/li>\n<\/ul>\n\n\n\n

    Its remarkable camouflage can make an adult extremely difficult to notice when resting motionless against a leaf.<\/p>\n\n\n\n

    Size<\/strong><\/h3>\n\n\n\n

    The greater angle-wing is one of the larger North American katydids. Adults measure roughly 52\u201363 mm, or about 2\u20132.5 inches, when measured along the body and wings.<\/p>\n\n\n\n

    Its extraordinarily long antennae make the insect appear even larger. Females may also look heavier through the abdomen, particularly when carrying mature eggs.<\/p>\n\n\n\n

    Why Does It Look Like a Leaf?<\/strong><\/h3>\n\n\n\n

    Leaf mimicry is one of this katydid’s most important defenses. The wings are green and covered with branching veins that closely resemble a living leaf.<\/p>\n\n\n\n

    When the insect remains still among foliage, its outline becomes difficult for birds and other predators to distinguish from the surrounding vegetation.<\/p>\n\n\n\n

    Habitat and Distribution<\/strong><\/h2>\n\n\n\n
    \"Habitat<\/figure>\n\n\n\n

    Greater angle-wing katydids are primarily tree-dwelling insects. They prefer places where deciduous trees, shrubs, and other broad-leaved vegetation provide food, shelter, and camouflage. They can live in natural forests as well as suburban landscapes. Adults are particularly noticeable in late summer and fall, when males begin calling and individuals sometimes visit lights or buildings.<\/p>\n\n\n\n

    Common Habitats<\/strong><\/h3>\n\n\n\n

    They may occur around:<\/p>\n\n\n\n

      \n
    • Deciduous forests<\/li>\n\n\n\n
    • Forest edges<\/li>\n\n\n\n
    • Tall shrubs<\/li>\n\n\n\n
    • Gardens<\/li>\n\n\n\n
    • Parks<\/li>\n\n\n\n
    • Orchards<\/li>\n\n\n\n
    • Wooded suburban yards<\/li>\n\n\n\n
    • Rural properties<\/li>\n\n\n\n
    • Tree-lined roads<\/li>\n\n\n\n
    • Vegetation around buildings<\/li>\n<\/ul>\n\n\n\n

      Greater angle-wings commonly remain high in trees and tall bushes, making them much easier to hear than to see.<\/p>\n\n\n\n

      Where Are Greater Angle-Wing Katydids Found?<\/strong><\/h3>\n\n\n\n

      The species occurs mainly in the eastern and southwestern United States. Its precise distribution differs from other members of the genus Microcentrum<\/em>.<\/p>\n\n\n\n

      Similar-looking angle-wing katydids occur farther west. For example, the California angle-wing katydid, Microcentrum californicum<\/em>, occurs in California and Arizona and can resemble the greater angle-wing.<\/p>\n\n\n\n

      What Do Greater Angle-Wing Katydids Eat?<\/strong><\/h2>\n\n\n\n
      \"What<\/figure>\n\n\n\n

      Greater angle-wing katydids spend much of their lives among leafy vegetation, where food is readily available. Like many katydids, they mainly use strong chewing mouthparts to consume plant material. Their feeding is generally scattered rather than concentrated, so individual katydids rarely cause serious damage to established trees or garden plants.<\/p>\n\n\n\n

      Greater Angle-Wing Katydid Diet<\/strong><\/h3>\n\n\n\n

      Possible foods include:<\/p>\n\n\n\n

        \n
      • Tree leaves<\/li>\n\n\n\n
      • Shrub leaves<\/li>\n\n\n\n
      • Tender plant tissue<\/li>\n\n\n\n
      • Flowers<\/li>\n\n\n\n
      • Soft stems<\/li>\n\n\n\n
      • Buds<\/li>\n\n\n\n
      • Pollen<\/li>\n\n\n\n
      • Fruits<\/li>\n\n\n\n
      • Seeds<\/li>\n\n\n\n
      • Occasionally small insects or other animal material<\/li>\n<\/ul>\n\n\n\n

        Their diet can vary according to available vegetation and life stage.<\/p>\n\n\n\n

        Do They Harm Plants?<\/strong><\/h3>\n\n\n\n

        Greater angle-wing katydids may chew irregular sections from leaves, but they are not generally regarded as major landscape pests.<\/p>\n\n\n\n

        A few individuals in a garden or tree usually cause little noticeable damage. Their feeding is part of the normal ecological interaction between insects and vegetation.<\/p>\n\n\n\n

        How Do They Feed?<\/strong><\/h3>\n\n\n\n

        Their mouthparts work by cutting and chewing rather than sucking plant sap. The insect often feeds along leaf edges or surfaces while remaining partly concealed.<\/p>\n\n\n\n

        Their coloration allows them to eat while still blending remarkably well into surrounding foliage.<\/p>\n\n\n\n

        Greater Angle-Wing Katydid Sound<\/strong><\/h2>\n\n\n\n

        The sound of the greater angle-wing katydid is one of the easiest ways to detect it. Males call from trees and shrubs, often from positions too high to inspect closely. Their song consists of high-pitched ticking sounds, and they can produce more than one type of call depending on whether they are attracting females or interacting with nearby males.<\/p>\n\n\n\n

        What Does the Sound Like?<\/strong><\/h3>\n\n\n\n

        The mating song consists of a rapid sequence of high-pitched ticks that becomes faster toward the end and may continue for several seconds.<\/p>\n\n\n\n

        Males can also produce a short, isolated sound at intervals. This second signal is thought to function in interactions between neighboring males.<\/p>\n\n\n\n

        How Does It Make Sound?<\/strong><\/h3>\n\n\n\n

        Male katydids make sound through stridulation<\/strong>. Specialized areas of the forewings are rubbed together, creating vibrations that produce the call.<\/p>\n\n\n\n

        Females can detect these signals and use them to locate calling males hidden among vegetation.<\/p>\n\n\n\n

        When Do They Call?<\/strong><\/h3>\n\n\n\n

        Calling is most common when adults are present during late summer and fall. BugGuide records adults as active from September through November in Michigan, although seasonal timing changes according to regional climate.<\/p>\n\n\n\n

        Warm evenings are often the best time to hear males.<\/p>\n\n\n\n

        Greater Angle-Wing Katydid Nymph<\/strong><\/h2>\n\n\n\n
        \"Greater<\/figure>\n\n\n\n

        Young greater angle-wing katydids are known as nymphs. They resemble small adults but do not yet possess fully developed wings. Their appearance changes considerably as they pass through successive molts, making nymph identification more difficult than adult identification.<\/p>\n\n\n\n

        Nymph Identification<\/strong><\/h3>\n\n\n\n

        A nymph generally has:<\/p>\n\n\n\n

          \n
        • Bright or pale green coloration<\/li>\n\n\n\n
        • Extremely long antennae<\/li>\n\n\n\n
        • Long hind legs<\/li>\n\n\n\n
        • No fully developed wings<\/li>\n\n\n\n
        • Small wing pads in later stages<\/li>\n\n\n\n
        • Slender abdomen<\/li>\n\n\n\n
        • Leaf-associated behavior<\/li>\n\n\n\n
        • Increasingly adult-like appearance after each molt<\/li>\n<\/ul>\n\n\n\n

          Older nymphs become easier to recognize as their developing wing structures become more obvious.<\/p>\n\n\n\n

          How Do Nymphs Grow?<\/strong><\/h3>\n\n\n\n

          Katydids undergo incomplete metamorphosis<\/strong>, meaning there is no caterpillar or pupal stage.<\/p>\n\n\n\n

          A newly hatched nymph feeds and grows until its exoskeleton becomes restrictive. It then molts, develops a larger body, and repeats this process several times before reaching adulthood.<\/p>\n\n\n\n

          Life Cycle and Reproduction<\/strong><\/h2>\n\n\n\n

          The greater angle-wing katydid generally completes its life cycle over roughly a year. Females typically lay eggs late in the warm season, and eggs commonly provide the overwintering stage in cooler regions. Nymphs emerge when favorable conditions return, grow through repeated molts, and eventually become winged adults that reproduce later in the season.<\/p>\n\n\n\n

          Life Cycle Stages<\/strong><\/h3>\n\n\n\n

          The main stages include:<\/p>\n\n\n\n
