Camel crickets are in the grasshopper\/cricket\/katydid order Orthoptera and in the family Rhaphidophoridae (pronounced Rap-he-doe-fore<\/strong>\u2019-a day<\/em>, says https:\/\/infinitespider.com<\/a>). In her original article, the BugLady placed them in the family Gryllacrididae, but she doesn\u2019t know if they\u2019ve been moved or if that was insufficient scholarship on her part. There are about 500 species of cave crickets in the world (they\u2019re absent from very cold areas), with 150 species in North America, and our greatest diversity is west of the Mississippi. The lunker of the North American crowd seems to be the Square-legged camel cricket<\/a>, which lives along the Pacific Coast and has a small body and a leg-spread of up to 8.\u201d<\/p>\n\n\n\n \u201cCamel cricket\u201d is self-explanatory; other names are cave cricket (because some species are cave specialists), spider crickets (because of their long, skinny legs), cave w\u0113t\u0101 (if you\u2019re in New Zealand), sand treaders (because some family members are specially adapted to tunnel deep into sand dunes), kamado-uma<\/em> and benjo korogi<\/em> (“toilet cricket,” if you\u2019re in Japan), Hogan bugs (no idea), and sprickets (spider + cricket).<\/p>\n\n\n\n <\/p>\n\n\n\n Camel crickets are not just nocturnal, they actively avoid light. They\u2019re often found in woodlands, in cool, dark, damp microclimates like leaf litter, stumps, in and under rotten logs, in caves, under dense ground cover, and in animal burrows. They also are at home in man-made structures like old mines, wells, sheds, stacks of firewood, crawl spaces, and basements (they tend to come indoors when it\u2019s too hot and dry for them outdoors); and one Asian species that likes greenhouses has, unfortunately, become a world traveler. A basement that has camel crickets is a basement that has dampness issues.<\/p>\n\n\n\n Our native species of camel crickets are all built from pretty much the same blueprint \u2013 small body, camouflage coloration, no wings, long spindly legs (they\u2019re great jumpers), and really long antennae. The spines on a male\u2019s legs are used to fight other males and to grasp females. Females have a straight, sturdy ovipositor (not a stinger) at the rear that\u2019s flanked by two cerci; males just have cerci. The nymphs, which resemble mini-adults, may look translucent. Not surprisingly, some camel crickets can be very hard to tell apart, except by an expert with a microscope.<\/p>\n\n\n\n Camel crickets are omnivores\/detritivores, and they eat fungus, bits of decaying plants and animals, plus the occasional live insect, including small camel crickets (see – they\u2019re actually helping to sanitize your basement!). Unfortunately, they sometimes nibble on papers and fabrics that are stored in basements.<\/p>\n\n\n\n They are important members of food webs because they make small pieces of food into even smaller pieces for even smaller animals, and they\u2019re eaten by many predators. Granted that they are startling-looking insects (that don\u2019t bite or sting); the species that do come indoors do very minor damage, and they rarely reproduce inside unless conditions are perfect, and yet the vast percentage of the internet hits are exterminator companies. Don\u2019t want camel crickets (or fishing spiders or Asian multicolored ladybugs or box elder bugs or house centipedes or brown marmorated stink bugs) in your house? Keep the basement dry and seal potential entrance holes around foundations, doors, and windows.<\/p>\n\n\n\n They are considered \u201cprimitive\u201d Orthopterans, but their sensory systems are first class. Their eyes probably distinguish light from dark and don\u2019t transmit images (animals that live in the dark don\u2019t need their eyes much), but other senses fill in the gap. Those long antennae are super-sensitive, giving them information about obstacles and air temperature and about the presence of passing cave crickets, who they find by touch in the darkness. Their cerci tell them about air currents, humidity, and temperature, and tiny hairs all over their bodies have nerve endings. Mouthparts called palps hold taste buds and, with the help of the antennae, aid in finding food, as do olfactory organs on their bodies. They can\u2019t hear \u2013 they are silent and therefore earless – but researchers are studying the role of vibrations in camel cricket communications.<\/p>\n\n\n\n <\/p>\n\n\n\n The BugLady isn\u2019t quite sure which species of camel cricket she photographed. They look like Spotted camel crickets (Ceuthophilus maculatus<\/em>) \u2013 a woodland species that\u2019s the most common species in the US \u2013 but they might also be Short-legged\/Boreal camel crickets (Ceuthophilus brevipes<\/em>), which like damper habitats.<\/p>\n\n\n\n Because they are nocturnal and secretive, parts of their biographies are still sketchy, but the (wonderful) animaldiversity.org<\/a> website offers a detailed account of the lifestyle of the closely-related Black-sided camel cricket<\/a> (Ceuthophilus latens<\/em>). Here\u2019s their description of its courtship:<\/p>\n\n\n\n \u201cMating takes place at night. …\u2026. If the antennae of two potential mates touch, the individuals will briefly \u201cfence\u201d and hit their antennae together. Males can identify females once a part of the female body comes into contact with the male antennae or palps. To initiate mating, a male backs toward a female and put his cerci underneath her abdomen. He clasps and unclasps his cerci, apparently trying to lift her abdomen above the ground. If the female does not immediately lift her abdomen, the male will crawl all over her body, feeling with his antennae, mouthparts, and cerci. He also vibrates his antennae. Females do not play an active role in courtship; they either mate or walk away \u2026 <\/em>[and if she disappears into the darkness, he does not follow]…. Copulation lasts 2 to 12 minutes, during which both males and females remain relatively inactive. The male passes spermatozoa to the female \u2026\u2026<\/em><\/p>\n\n\n\n Ceuthophilus latens is polygynandrous, with both males and females mating with many individuals. \u2026.. If a non-mating male approaches a mating pair during copulation, the male will defend his mate, even dragging the female along to do so. \u2026.. Ceuthophilus latens females are known to practice sexual cannibalism on males. A female sometimes will eat the head of her mate while the male is still alive. This likely occurs when the female is hungry and the male mate is particularly weak. One study showed that all C. latens males had died within two weeks of copulation, while the females in the study continued to thrive. In another study, the bodies of males left with large groups of females were later found to be shells with the soft parts eaten away.\u201d<\/em><\/p>\n\n\n\n Researchers have discovered that some camel crickets seem to deploy and to sense pheromones (chemical scents) but are unsure if\/how these may be used in courtship.<\/p>\n\n\n\n The female lays a few eggs at a time in a few different locations, maybe up to 60, but no one knows for sure, using her sensory cerci to determine whether the site has the right temperature and humidity, and she dies several days after she lays her final eggs. Camel crickets may overwinter either as nymphs or adults, and they may live as long as two years.<\/p>\n\n\n\n Fun Camel Cricket Fact #1: A carving of a camel cricket dating from 17,000 to 12,000 years ago was found in a cave in France, suggesting a long cohabitation with humans.<\/p>\n\n\n\n Fun Camel Cricket Fact #2: As one website said, \u201cThey don’t bite, they spend a lot of time cleaning themselves, and so are quite clean, despite their wet-looking fawn coloring.\u201d<\/em> Another suggested that they make good pets.<\/p>\n\n\n\n For more information about these fascinating insects: there is a wonderful chapter about them in Broadsides from the Other Orders<\/span> by Sue Hubbell. The BugLady recommends this article posted on what seems to be a neat website on “Meet the Camel Cricket<\/a>” by the Infinite Spider, and this one (which she hopes is not behind a paywall), despite its overly-long \u201cEEK-I-see-a-Bug!\u201d intro, “Out of the Darkness<\/a>” by The Washington Post. The authors have some interesting thoughts about how many insects it takes to support the human population of the globe and how close we might be getting to that particular tipping point.<\/p>\n\n\n\n The BugLady<\/em><\/p>\n","protected":false},"excerpt":{"rendered":" Note: Most links leave to external sites Howdy, BugFans, BugFan Carl sent the BugLady a \u201cWhat-is-it?\u201d picture recently of an insect that had met an untimely end in his basement.
