Pill bugs also known as Sow bug or roly-poly are not insects, but are Isopods. Pill bugs have 7 pairs of legs and 7 body segments not including the head. Their antennae are sharply curved. Pill bugs are a dark grey with a little bit of brown. Some appear to be almost black. Pill bugs are covered by a hard exoskeleton made from chitin. Pill bugs are less than an inch long. Most species will curl up into a ball when threatened hence the name Pill bug or Roly-poly. Pill bugs feed on decaying plants and animals and some living plants.
Earwigs are easily identified by the pincers at the rear. They are also called Pincher bugs for this reason. There are tales that state these insects will burrow into your ears at night and lay their eggs. There is no truth to this myth. The male pincers are more curved than the female. The pincher is use for defence and will not harm you if handled. The common earwig is around 5/8 inch long and dark brown in color with a reddish head and pale yellow legs. earwigs can be found outdoors in dark, cool, moist places. They end up indoors accidentally when looking for food, water and shelter. They will not cause any damage indoors. Earwigs will release a foul odor when handled.
Crickets are dark brown to black in color. They are 9/16 to over 1 inch long. Adults have wings but are not great at flying. The female is easy to spot because she has a ovipositor at the rear of abdomen. This looks like a long sword coming from rear. This is used to deposit eggs into soil. Eggs hatch in 15 to 25 days and the nymphs look like adults with the exception of being smaller and not having wings. Nymphs become adults in about 12 weeks. As many as 3 generations can be produced in a single year. Males attract females by rubbing their forewings together. This makes the chirping sound we are all familiar with. Crickets prefer dark, cool, moist places. They are more active at night and like feeding on organic material. They are also attracted to light.
There are about 18 different species of scorpions found in New Mexico. Most stings from scorpions are not considered life threatening with the exception of the Bark scorpion. Scorpions have 4 pairs of legs and 1 pair of pincers. Scorpions have several body segments with a segmented tail that has stinger at the tip. Scorpions are predatory and use both their pincers and stinger to subdue prey and fight off any enemies. They are nocturnal by nature but can be seen during the day. Scorpions prefer dry, warm, shady areas and can be found hiding under objects such as wood and rocks. They feed off other insects. Scorpions have the ability to climb rough surfaces and have been known to fall through roof pipes and vents.
Some cool facts about Centipedes
Though Centipedes inhabit almost every corner of the Earth, most people don't know much about the "100 leggers". The House Centipedes sometimes startles people by showing up in bathtubs or sinks, but this is only 1 of an estimated 8,000 species. Here is some cool facts about Centipedes.
1. Centipedes are the only arthropods known to have "poison claws" for subduing prey.The legs on the first segment of a centipede are not for walking. Instead, they're modified to form venomous fangs, which they use to inject paralyzing venom into prey.
2. Centipedes do not have "one hundred legs," centipedes have significantly less or more than 100 legs. Depending on the species, a centipede can have as few as 15 pair of legs, or as many as 171 pairs. Regardless of species, centipedes always have an odd number of leg pairs.
3. Centipedes have one pair of legs per body segment. This is the easiest way to tell the difference between a centipede and a millipede. Millipedes have two pairs of legs on most body segments.
4. Centipedes can live for several years. It is not unusual for a centipede to live 2-3 years, and some species survive longer than 5 years. Centipedes continue to molt and grow during their adult life, unlike insects.
5. Centipedes can regenerate lost legs. When under attack, a centipede will simply sacrifice a leg or two in order to escape. Since centipedes continue to molt as they grow as adults, they can regrow their legs.
6. Centipedes are prone to dehydration. Centipedes lack a waxy coating on the cuticle to help prevent water loss. This is important to know, cause this tells us they need moisture. To prevent dehydration centipedes like to hide under objects to help contain moisture. Wood, logs, leaf piles, trash, and under surface soil are all common areas where centipedes hide.
7. Most Centipedes are built for speed. With the exception of the slow-moving soil centipedes, which are built to burrow, these guys can run fast.
