They live outdoors usually on the ground but as winter season sets in; they can be found inside the buildings. They can be seen around the doors, windows, and garages. Some also build temporary burrows. Since they have no permanent place to live, they are sometimes seen in fields, woodland or other grassy areas. Hunting It is also known as a hunting spider because one of its characteristics is the ability to hunt on the ground.
b) Cellar Spiders The second common house spiders are the cellar spiders. They are long bodied spiders. You mostly find in dark places such as basements, cellars and crawl places. They also build webs on the ceiling boards or floor. They mostly target the corners.
Chondrichthyes vs Arthropod The black widow is most easily recognized by the hourglass marking on the underside of its abdomen. When bitten, a neurotoxin is released that can cause dull pain and cramping in muscles, that can be accompanied by sweating and vomiting. Less than 1% of black widow bites result in death. Black widow spiders are usually not aggressive. If disturbed, they will retreat to a corner of their web.
This genus is famous for having spiders with a poisonous bite (Preston-Mafham 1984). Black Widow Spider http://pubs.ext.vt.edu/444/444-422/444-422.html Physiology (Muscles/skeletal/locomotion) The spider’s body is relatively simple. Similar to the rest of the species in Arthropoda, the spider has an exoskeleton that protects it from its environment. This exoskeleton protects the entire body of the spider that includes two segmented sections (the cephalothorax and the abdomen), as well as the four pairs of legs. An example of sexual dimorphism in the Southern Black... ... middle of paper ... ...itude towards spiders is favorable… Although many people, especially in the West, feel a high degree of revulsion towards spiders and may in fact be frightened by them” (Mafham 1984).
Blow fly Include a number of species including the common bluebottle fly, Calliphora vomitoria (Linnaeus) the green bottlefly, Phaenicia sericata (Meigen) and others. Adult flies are metallic blue, green, copper or black colored flies that otherwise resemble house flies in appearance. Adult:Blow flies are a diverse group ranging from 6 to 14 mm in length and generally having a metallic sheen to their bodies. The black blow fly has a dark, olive-green body, black legs, and orange pubescence around the mesothoracic spiracles. The secondary screwworm fly also has a green body, but its head is predominantly orange.
One of the main day time roosts and nursery roosts for bats are in buildings, where house cats are common. Houses and attics having small places to get out of, it makes the bat an easy target and catch for cats. Most predators take into consideration that bats hibernate, and they do it in large groups. During the winter while asleep, they are likely to be eaten by fishers, hawks and snakes.
The most well known wolf spider is the tarantula. These spiders can reach up to ten inches in their complete lengths. And although lore has it that they are one of the most poisonous spiders, their bites are only painful to humans, not deadly. (Biology of Spiders, R.Foelix) Though feeding habits vary with spiders their methods of reproduction are all relatively similar, though each species has its own specific ritual. Because spiders are cannabilistic, the much smaller male must be very cautious in approaching a potential mate.
The females always have a smaller upper body and a bigger abdomen than the males. The abdomen of the females is obviously larger on account of the ovary which swelling at the time of their fecundation gives them a more attractive appearance than the males. Spiders are not all of equal in productivity to be some having only seven or eight eggs in a bag whilst others have 50 100 or even 150 in each bag, which are seven eight or ten in a number insomuch that one female may lay a thousand eggs in a summer. The care of the eggs and young devolves upon the females only differ in the various species but in most as in other insects, their eggs being hatched by the warmth of the air alone without incubation.
Literature review: Thrips palmi Karny 1. Introduction Thrips (order: Thysanoptera) are minute fringe-winged insects that are difficult to spot via naked eyes. Adults thrips are generally about 1.5mm long and they have a slender elongated body (UC IPM, 2014). Using their asymmetrical paired mouth, they feed by piercing the epidermal layer of the host plant tissue and then suck out the sap (Hodges et al., 2009). Currently, only 7000 species of thrips have been identified and described in the world.
Finally, the genus of the South Black Widow spider is Latrodectus. This genus is famous for having spiders with a poisonous bite (Preston-Mafham 1984).

Similar to the rest of the species in Arthropoda, the spider has an exoskeleton that protects it from its environment. This exoskeleton protects the segmented sections of the body (the cephalothorax and the abdomen) as well as the four pairs of legs (Foelix 1996).
