how often do Mexican Red-Kneed Tarantula give birth?

The mating season, lasting from September to October, is followed by a nine-month gestation period after which 600- 700 eggs are laid and wrapped in a silky cocoon which the female, alone, guards aggressively. The mother tolerates the babies for a short period of time in which she might even feed them regurgitated food, but very briefly. Within a matter of weeks, or certainly by the time the female has her next molt, the babies are on their own. The mortality rate is very high and ants are a major menace. The life span of the female is thought to be 15- 25 years and possibly more than that. The male lives a much shorter time, not only because the female sometimes eats him, but more frequently because he does not molt correctly, or cannot escape his molt for some reason. Also, the male is usually the one seeking to mate, and so is more exposed to predictors.

Once a year.  They grow them in the summer and fall, and shed them after mating season.

Multimammate rats (also called multimammate mice) in the genus Mastomys have 24 nipples.  Litters sizes are often greater than 12 per female (though each female could presumably manage 24 offspring).  Sexual maturity is reached in 50-60 days.  They can get pregnant again right after birth.  Gestation is just over 30 days.\n\nSo, assuming a 50-50 sex ratio, no mortality, and unlimited resources, a single reproductive pair could generate a population size of 268,586 in one year.

Most of the 800 species of true tarantulas are black and brown with some variation of color on the knees and elsewhere. The Chilean Rose Hair and the Mexican Red Knee are most commonly pets. A tarantula costs $20 to $40 but adults can cost several hundred dollars and housing for the spider costs another $40. The Giant White Knee, Chaco Golden Knee, and Brazilian Salmon Pink Birdeater are also commonly used as pets.

I just found out that Canadian scientists have found that a few women ovulate twice a month and others have the biological potential to do so. Hope this helps.

Scorpions are among the few arthropods that don't lay eggs. In some, the female can store sperm until she is ready to fertilise her eggs. The fertilised eggs develop into embryos in brood chambers within the mother's body. Nutrients are transferred from the mother's digestive system to the embryos, but not through a placenta like in mammals. "Gestation" is quite long: it can take several months to more than a year before the young are "born". In some, the babies are fully formed but their skin remains white and soft until their second moult. In others, the babies look like fat white maggots with tiny pincers. They only look like scorpions after their second moult, when they get the right shape and their exoskeleton turns dark and hard

Red wasp (scientific name Polistes carolina) will hibernate over the winter in trees (usually dead).  More specifically it is only the breeding female that will hibernate while the rest of the colony will die off.  The female will be impregnated with sperm from the male so when she awakens in the spring a new generation will be born from the previous years copulation.

I saw that someone answered that tarantulas are omnivores (meaning that they eat both animal and plant matter).  This is incorrect.  Most tarantulas are insectivores (they eat insects).  Some are considered carniverous however because they are large enough and do attack small mamals and birds.  Tarantulas really couldn't be omnivores because of their mouth structure.  It would be implausible for them to eat plant matter.  They are oviparous, meaning they lay eggs.  They lay the eggs in a cacoon-like egg sack which the female will carry with her in most species.  The eggs usually hatch in 4-6 weeks, depending on the species.  Hope this answered your question.

In Mexico we called them "cuates" (plural) and they are not twins, they are not identical. This happens when two eggs are fertilized by two different sperms. As the other person said whether they are from different dads (natural way), or she got pregnant, in vitro and two sperms fertilized two of her eggs.\nOr as the other person said they could have been born one monday of any month and the other baby other monday of other month. But it's the same day.\nOr what happenned?

Breeding starts when the female sheds her old skin.  This releases pheromones that attract the male.  They will form a pair bond and hunt together as well as protect 20-50 mounded eggs.\n\nThey reach sexual maturity in 5-6 years and will mate in January.

This is an arboreal family who have sticky pads at the tips of their digits to help them climb. The best time to catch them is after a rain when they come down to mate and lay eggs, usually at the nearest stream. \n\nPictures at this website: http://www.geocities.com/slowloris9/amphibia/rhacopho/rhacopho.htm

The life cycle of the ant consists of four stages: egg, larva, pupa, and adult. Fertilized eggs produce female ants (queens, workers, or soldiers); unfertilized eggs produce male ants. \nEgg: Ant eggs are oval shaped and tiny (they are on the order of 1 mm long, but the queen's egg is many times larger). \n\nLarva: The worm-like larvae have no eyes and no legs; they eat food regurgitated by adult ants. The larvae molt (shed their skin) many times as they increase in size. \n\nPupa: After reaching a certain size, the larva spins a silk-like cocoon around itself (against a solid object, like the wall of the chamber) and pupates. During this time the body metamorphoses (changes) into its adult form. \n\nAdult: The pupa emerges as an adult. The entire life cycle usually lasts from 6 to 10 weeks. Some queens can live over 15 years, and some workers can live for up to 7 years.

Gestation is 510 to 730 days. Attached is a table of gestation periods for animals.

No periodical cicadas are expected to emerge in 2006. Next year, however, the 17-year cicadas will make an appearance in eastern Iowa, northern Illinois, southern Wisconsin, and along the southern edge of Late Michigan. Dense populations of this brood (Brood XIII) will emerge in farm-edge woods along rivers as well as in suburban Chicago backyards and forest preserves.

Their legs are specially designed to hold onto human head hair, they lay eggs (nits) that hatch in two weeks, they can be spread to anything your head touches (your hands, pillows, hats, other people, or even in your carpet).
