Desert Scorpion

Desert Scorpion

Desert Scorpion (Hadrurus arizonenis) The Desert Scorpion has one of the longest life spans of all scorpion species. It is also called the Giant Desert Hairy Scorpion and the North American Hairy Scorpion. Description: Desert Scorpions are the largest scorpions in North America. They are between four and seven inches long. On average they only weigh 0.18 ounces. Males and females are similar in appearance. They have excellent eyesight. They are tan to olive-green in color with a darker back and yellow pedipalps, legs, and tail. They have tiny erect hairs covering their whole bodies through which they detect vibrations in the air (sound) or ground. It is what allows them to track their prey. Like all scorpions, Desert Scorpions are considered arachnids like spiders. Arachnids are identified as having eight legs, no wings, and no antennae. Scorpions have three body segments. The prosoma or cephalothorax (head) that contains the eyes, the mouth and the pedipalps that look almost like claws with pinchers on the end called chelae. The main body, called the mesosoma, is actually seven segments. This section is where the four pairs of clawed walking legs are attached and also contains all the major body organs. The characteristic tail section is called the metasoma and it is five segments ending in the telson that contains a pair of venom glands and the stinger. Desert Scorpions are nocturnal. They live in abandoned burrows, crevices and small caves where they are protected from daytime heat. They hibernate in winter. Caves are a favorite dwelling because the temperature is naturally balanced and they are also home to many prey species....
Madagascar Hissing Cockroach

Madagascar Hissing Cockroach

Madagascar Hissing Cockroach (Gromphadorhina portentosa) Madagascar Hissing Cockroaches are native to the island from which it gets its name – Madagascar. Madagascar Hissing Cockroaches are 2 to 3 inches long and weigh up to 0.8 ounces. These amazing insects are nothing like the cockroaches that inhabit human dwellings. In fact, 99% of cockroach species do not inhabit human dwelling. DESCRIPTION: Madagascar Hissing Cockroaches are brown and oval shaped. Their exoskeleton is hard, waxy and very thick. Like other insects they have six legs. They do not have wings and they have two antennae. Males also have “horns” on their heads that they use to battle other males. They are not the typical “horns” as seen on hoofed mammals. These “horns” are more like large bumps, or tubercles, behind their heads. They are sometimes called prenatal humps. However, like a hoofed mammal with horns they will use the “horns” to push other males around while competing to protect resources.  When battling, the males emit their distinctive hissing sound and the winner hisses even louder over his victory. They make the hissing sound by expelling air through their breathing spiracles on their abdomens. Hissing is also part of their mating rituals and is used as a cry of alarm. Most insects make sounds by rubbing body parts together so making sound via air expulsion is unique to the Madagascar Hissing Cockroach in the insect world. They are nocturnal. They forage for food on the forest floor at night. During the day they hide under leaves, logs, and other forest debris. RANGE:  They are only found on the island of Madagascar, which...
