A Texas katydid<\/strong> can be anything from a delicate green leaf mimic to a large, red-eyed predatory insect. Texas supports numerous katydid species, including bush katydids, coneheads, meadow katydids, anglewings, and the unusual Central Texas leaf-katydid. Most have extremely long antennae, powerful jumping legs, and distinctive nighttime calls. Some species are mainly plant eaters, while others are aggressive predators of insects. Their size, color, sound, habitat, and seasonal activity make Texas katydids surprisingly diverse and easy to encounter.<\/p>\n\n\n\n

What Does a Texas Katydid Look Like?<\/strong><\/h2>\n\n\n\n

Katydids belong to the family Tettigoniidae and are close relatives of crickets and grasshoppers. Texas A&M describes them as generally medium to large insects measuring roughly 1 to 2.5 inches<\/strong>, with long threadlike antennae and powerful hind legs. Depending on species, they may be bright green, brown, reddish, or patterned.<\/p>\n\n\n\n

Texas Katydid Identification<\/strong><\/h3>\n\n\n\n

Common characteristics include:<\/p>\n\n\n\n

    \n
  • Extremely long, thin antennae<\/li>\n\n\n\n
  • Large hind legs for jumping<\/li>\n\n\n\n
  • Green, brown, red, or mixed coloration<\/li>\n\n\n\n
  • Leaflike wings in many species<\/li>\n\n\n\n
  • Chewing mouthparts<\/li>\n\n\n\n
  • Wings that may be long or reduced<\/li>\n\n\n\n
  • Sword-shaped ovipositor in many females<\/li>\n\n\n\n
  • Nighttime calling by adult males<\/li>\n<\/ul>\n\n\n\n

    Long antennae are one of the easiest ways to distinguish katydids from most grasshoppers, which usually have much shorter antennae.<\/p>\n\n\n\n

    Green and Brown Katydids in Texas<\/strong><\/h3>\n\n\n\n

    Many Texas katydids are green because this coloration provides excellent camouflage among leaves and grasses. Brown individuals can blend with dry vegetation, bark, and dead leaves.<\/p>\n\n\n\n

    Some species naturally occur in more than one color form, so finding a brown katydid in Texas<\/strong> does not necessarily mean it represents a separate species.<\/p>\n\n\n\n

    Common Texas Katydid Species<\/strong><\/h2>\n\n\n\n
    \"Common<\/figure>\n\n\n\n

    Texas contains several distinct katydid groups occupying habitats ranging from wetlands and forests to dry brush country. Representative species include coneheads, false katydids, true katydids, and predatory katydids.<\/p>\n\n\n\n

    Central Texas Leaf-Katydid<\/strong><\/h3>\n\n\n\n

    The Central Texas leaf-katydid<\/strong> (Paracyrtophyllus robustus<\/em>) is also known as the truncated true katydid or red katydid.<\/p>\n\n\n\n

    It is particularly associated with Central Texas and is primarily tree-dwelling. It feeds heavily on oaks, and isolated individuals are commonly green while outbreak populations can contain many pinkish or red insects.<\/p>\n\n\n\n

    Its call is a short, raspy series of notes lasting roughly one-third of a second. When hundreds of individuals sing simultaneously, their combined calls can create an almost continuous pulsating sound.<\/p>\n\n\n\n

    Greater Anglewing Katydid<\/strong><\/h3>\n\n\n\n

    The greater anglewing, Microcentrum rhombifolium<\/em>, is another recognizable Texas species. Its broad green wings resemble leaves and provide effective camouflage.<\/p>\n\n\n\n

    Its song consists of a rhythmic sequence of roughly 20 evenly spaced ticking sounds. Several Microcentrum<\/em> species occur in or near Texas.<\/p>\n\n\n\n

    Broad-Tipped Conehead<\/strong><\/h3>\n\n\n\n

    The broad-tipped conehead, Neoconocephalus triops<\/em>, occurs across most of Texas except the Panhandle. It can be green or brown and has the characteristic elongated head associated with conehead katydids.<\/p>\n\n\n\n

    Its call is a nearly continuous, thin buzzing sound. In Texas, it may be encountered relatively early in the year, particularly from about February through May.<\/p>\n\n\n\n

    Giant Texas Katydid<\/strong><\/h2>\n\n\n\n
    \"Giant<\/figure>\n\n\n\n

    The insect commonly called the giant Texas katydid<\/strong> is often the greater arid-land katydid, Neobarrettia spinosa<\/em><\/strong>. It is also known as the red-eyed devil<\/strong> because of its striking eyes and intimidating appearance.<\/p>\n\n\n\n

    Unlike many leaf-eating katydids, this species is a spiny predatory katydid and is notably large and powerful.<\/p>\n\n\n\n

    Giant Texas Katydid Size<\/strong><\/h3>\n\n\n\n

    Adult greater arid-land katydids reach impressive dimensions:<\/p>\n\n\n\n

      \n
    • Males:<\/strong> About 34\u201345 mm<\/li>\n\n\n\n
    • Females:<\/strong> About 44\u201352 mm<\/li>\n\n\n\n
    • Build:<\/strong> Large and heavily spined<\/li>\n\n\n\n
    • Eyes:<\/strong> Distinctively red<\/li>\n\n\n\n
    • Activity:<\/strong> Mainly warm-season<\/li>\n\n\n\n
    • Range:<\/strong> Much of Texas into southeastern Arizona<\/li>\n<\/ul>\n\n\n\n

      Females can therefore exceed 2 inches in body length<\/strong>, making this one of the more imposing katydids likely to be encountered in Texas.<\/p>\n\n\n\n

      Where Does the Giant Texas Katydid Live?<\/strong><\/h3>\n\n\n\n

      The greater arid-land katydid occurs from the Red River south to the Rio Grande and extends west into southeastern Arizona. It favors oak-juniper woodland, mesquite, brush, and arid landscapes<\/strong>. Adults and nymphs may be encountered from spring into fall.<\/p>\n\n\n\n

      What Does the Giant Texas Katydid Eat?<\/strong><\/h3>\n\n\n\n

      Unlike katydids that primarily feed on foliage, Neobarrettia spinosa<\/em> is strongly omnivorous and predatory.<\/p>\n\n\n\n

      It has powerful mouthparts and may capture insects and other small prey. Its sturdy legs and prominent spines give it a noticeably more formidable appearance than ordinary leaf katydids.<\/p>\n\n\n\n

      Texas Katydid Sound<\/strong><\/h2>\n\n\n\n

      Texas evenings can be filled with katydid songs. Male katydids produce sound by rubbing specialized structures on their wings together, a process known as stridulation. Females detect these signals using hearing organs located on their front legs.<\/p>\n\n\n\n

      What Does a Texas Katydid Sound Like?<\/strong><\/h3>\n\n\n\n

      The exact sound depends on species:<\/p>\n\n\n\n
