it is a hermaphrodite...this also occurs in many invertebrates including flatworms and some earthworms.  \n\nremember that a hermaphrodite does not mean that it mates with itself spontaneously, though.  it still needs a mate, but it can serve as either a male or female since it has both sets of reproductive organs.

sugar & grease is what ants are usually attracted to.\n\nput out a potato chip & watch them go wild (it's the grease in the potato chip that they are after)

Here is a great website for that sort of research. It has a taxonomic chart with hyperlinks to information, pictures, sounds, and specimens. There are more than a dozen phylums of 'worms' represented with many photos to help with identification. \n\nhttp://animaldiversity.ummz.umich.edu/site/accounts/classification/Animalia.html

HAHAHAHAHAHA omg... seeing all your other questions then seeing this one? TOO FUNNY! ... Thanks Darius I needed to laugh today:)\n\nOkay, okay, okay, here is my real answer hope it helps....\n\nHow do porcupines make love? You would probably think the answer is "very carefully," but you would probably be wrong. The answer is more improbable and much more bizarre than that. I will explain further.... So the next time a friend asks you how porcupines make love, you can set them straight by describing these events (in as much detail as you dare). \n\nAnimals...\nIn the 1940's some ppl did a study on the sex life of a porcupine. They were kept in the Biology Dept. at the University of Buffalo. The colony consisted of 5 females (Maudie, Nightie, Prickles, Snooks and Skeezix) and 3 males (Old Dad, Pinkie,[1] and Johnnie).\n\nHere is what the found out about the Females:\n\nIt was noted that the animals of both sexes objected to being stroked or having their feet, tail base, or genitals touched by the authors. In July/August, as the mating season approached, the female porcupine would often rub her genitals on structures such as food and water dishes, sticks, and the cage wire. As the season progressed she sought and accepted more frequent tactile stimulation (presumably from the human investigators). As the mating season approached, young females become more nervous and excited and put more "vim, vigor and action" into their activities. They would even "seize, straddle, and ride sticks about the cage" walking erect and stimulating their genitalia with the stick. This period of excitement was followed by a stage the female went off her food, remained close to the male and "moped." During this period the female even accepted the insertion of a thermometer into the vagina (which she resisted at other times). \n\nAnd the male behavior:\n\nWhen placed in a cage with a female the male porcupine toured the whole area rubbing everything with his nose. He carefully smelled all items, paying closest attention to objects that had been in contact with the female and the places where she had urinated. He often walked about the cage on three legs, clutching at his genitals with his free left front paw. Like the females, the male rubbed his genitals on objects in the cage, and it appeared that the larger the object the more attractive as a rubbing place. The authors describe having to remove a one and a half inch spike from the frame of one cage as they feared that the animal’s vigorous rubbing would result in injury. Males also indulged in "stick riding" as described for females. Males would often "sing"[2] during this period and became more aggressive with other males. When the male encountered the female porcupine he smelled her all over, then reared up on his hind legs, his penis fully erect. If the female was not ready she ran away. If she was prepared for mating she also reared up and faced the male, belly-to-belly. In this position most males then sprayed the female with a strong stream of urine,[3] soaking her from head to foot.[4] She would either 1) object vocally, 2) strike with her front paws, as though boxing, 3) threaten or try to bite, or 4) shake off the urine and run away. If ready for mating the female did not object strongly to this shower. This courtship routine occurred several times in the days or weeks leading up to copulation. \n\nMating:\n\nMating occurred in November or December. While females at the peak of receptivity would accept any male, males required a period of close association with the females before they would mate with them. The male made sexual contact from behind the female. The spines of both animals were relaxed and lay flat. His thrusts were of the "usual nature" and were produced by flexing and straightening the knees. Males did not grasp the female in any way. Mating continued until the male was exhausted. Each time he broke awa

http://en.wikipedia.org/wiki/Parelaphostrongylus_tenuis\n\nMorphology\n\nRoundworms are triploblastic protostomes with a complete digestive system. Roundworms have no circulatory or respiratory systems so they use diffusion to breathe and for circulation of substances around their body. They are thin and are round in cross section, though they are actually bilaterally symmetric. Nematodes are one of the simplest animal groups to have a complete digestive system, with a separate orifice for food intake and waste excretion, a pattern followed by all subsequent, more complex animals. The body cavity is a pseudocoel (persistent blastula), which lacks the muscles of coelomate animals used to force food down the digestive tract. Nematodes thus depend on internal/external pressures and body movement to move food through their digestive tracts. The mouth is often surrounded by various flaps or projections used in feeding and sensation. The portion of the body past the anus or cloaca is called the "tail." The epidermis secretes a layered cuticle made of keratin that protects the body from drying out, from digestive juices, or from other harsh environments, as well as in some forms sporting projections such as cilia that aid in locomotion. Although this cuticle allows movement and shape changes via a hydrostatic skeletal system, it is very inelastic so does not allow the volume of the worm to increase. Therefore, as the worm grows, it has to moult and form new cuticles. The cuticles don't allow volume to increase so as to keep hydrostatic pressure inside the organism very high. For this reason, the roundworms do not possess circular muscles (just longitudinal ones) as they're not required. This hydrostatic pressure is the reason the roundworms are round.\nMost free-living nematodes are microscopic, though a few parasitic forms can grow to several meters in length. There are no circular muscles, so the body can only undulate from side to side. Contact with solid objects is necessary for locomotion; its thrashing motions vary from mostly to completely ineffective at swimming.\nRoundworms generally eat bacteria, algae, fungi and protozoans, although some are filter feeders. Excretion is through a separate excretory pore.\nReproduction is usually sexual. Males are usually smaller than females (often very much smaller) and often have a characteristically bent tail for holding the female for copulation. During copulation, one or more chitinized spicules move out of the cloaca and are inserted into genital pore of the female. Amoeboid sperm crawl along the spicule into the female worm.\nEggs may be embryonated or unembryonated when passed by the female, meaning that their fertilized eggs may not yet be developed. In free-living roundworms, the eggs hatch into larva, which eventually grow into adults; in parasitic roundworms, the life cycle is often much more complicated.\nRoundworms have a simple nervous system, with a main nerve cord running along the ventral side. Sensory structures at the anterior end are called amphids, while sensory structures at the posterior end are called phasmids.\n\nhttp://en.wikipedia.org/wiki/Nematode\n\n\nHope that helps!

Boy, i having hear this for a very long time...A spanish fly is something that a guy will slip into a girls drink, so he can have sex with her...Only a PIG would do this to a girl,because thats the only way these Pigs can get sex...Just a bunch of dirty nasty PIGS....\n Clowmy

Soon after mating, impregnated females deposit fertilized eggs by dipping their abdomens into shallow water alongside vegetation, or into soft muck. The eggs undergo a maturation over winter and hatch into larvae the next spring. The ugly larvae have been called little "dirt balls" since dirt clings to the hairs that cover their bodies. They are voracious aquatic predators feeding night and day (the larva at the left was cleaned up for the photograph by Lauren Pintor). They capture their food by means of a hinged lower lip that can be flipped forward to trap prey on stiff bristles. The lip can be extended about a third of the length of the larva's body, giving them enough reach to even capture small fish. Larvae breathe by means of gills inside the anal chamber, into which water is pumped, then forcibly expelled. \n\nOver a 3-4 year period, larvae molt many times as they grow their way toward adulthood and an aerial existence. When they reach a pre-adult stage, they stop feeding and crawl out of the water onto vegetation, where they gulp air to inflate and expand their bodies. They break out of their larval skin and next inflate their wings, which become outstretched. Thereafter they wait as their body parts dry. Then they take flight to feed on other flying insects some distance from their watery birthplace. \n\nThe adults live for only 4-7 weeks. After vigorous daylight feeding on mosquitoes, deerflies, flying ants, and whatever they can capture in flight, females return to water after copulating to lay their eggs. Males join them and patrol the swale or pond where eggs are being deposited. It is a short, but intense, adulthood of feeding, sexual interaction, and egg deposition.

Here's one theory:\n\nWomen who work or live together tend to get their menstrual cycles in sync. That curious phenomenon known for years by scientists and many ordinary folk, has long been suspected as an indication that humans, like insects and some mammals, communicate subtly by sexual aromas known as pheromones.

omg- this is such a complex thing. i just took a parasite class and we talked about nothing but worms and amoebas. worms normally enter through digestion and then burrow their heads between villi. then it grows and matures and deposits eggs through feces. some worms use proglottids, some drop eggs directly into intestines. the eggs are then released out of the anus and ready for another host or vector. some worms end up going though the lamina propria in intestines and getting into hepatic duct and getting into the blood stream. worms can then get into the heart or even encyst in muscle and crippling the muscle if enough get in there. the trichino worm gets into arm muscles and enough render the arm useless.

All animals release pheromones, or perfumes, that attract others, show dominance, etc. So insects attract others this way and then mate. While the fertilization is the same, the mating process is different for many insects. However, many times the female may eat the male.

During mating season, males may court a female by nuzzling her head or by gently biting the back of her neck and rear flippers. If the female does not flee, the male attaches himself to the back of the female's shell by gripping her top shell with claws in his front flippers. He then folds his long tail under her shell to copulate. \n\nFemales observed on the nesting beach after recently mating often have scratched shells and may be bleeding from where the males' were hooked to their shells. Copulation can take place either on the surface or under water.

there part of a group of insects that only live a short while, a few weeks or more. so they have to find a mate quickly and reproduce, just nature thats all.
