A hiatal hernia occurs when the stomach pokes above the diaphragm into the chest. An umbilical hernia occurs at the belly button (umbilicus) and is most commonly seen in infants.

Mosquitoes are small, midge-like flies which comprise the family Culicidae. Females of most species are ectoparasites, whose tube-like mouthparts (called a proboscis) pierce the hosts' skin to consume blood.arvae of the non-biting Toxorhynchites mosquitoes are also natural predators of other Culicidae. Each larva can eat 10 to 20 mosquito larvae per day. During its entire development, a Toxorhynchites larva can consume an equivalent of 5,000 larvae of the first-instar (L1) or 300 fourth-instar larvae (L4).
