Botfly :: Botfly (n.) A dipterous insect of the family (Estridae, of many different species, some of which are particularly troublesome to domestic animals, as the horse, ox, and sheep, on which they deposit their eggs.

Gid :: Gid (a.) A disease of sheep, characterized by vertigo; the staggers. It is caused by the presence of the C/nurus, a larval tapeworm, in the brain. See C/nurus..

Sporocyst :: Sporocyst (n.) An asexual zooid, usually forming one of a series of larval forms in the agamic reproduction of various trematodes and other parasitic worms. The sporocyst generally develops from an egg, but in its turn produces other larvae by internal budding, or by the subdivision of a part or all of its contents into a number of minute germs. See Redia..

Strepsipterous :: Strepsiptera (n. pl.) A group of small insects having the anterior wings rudimentary, and in the form of short and slender twisted appendages, while the posterior ones are large and membranous. They are parasitic in the larval state on bees, wasps, and the like; -- called also Rhipiptera. See Illust. under Rhipipter..

Paedogenesis :: Paedogenesis (n.) Reproduction by young or larval animals.

Bark Beetle :: Bark beetle () A small beetle of many species (family Scolytidae), which in the larval state bores under or in the bark of trees, often doing great damage..

Appendicularia :: Appendicularia (n.) A genus of small free-swimming Tunicata, shaped somewhat like a tadpole, and remarkable for resemblances to the larvae of other Tunicata. It is the type of the order Copelata or Larvalia. See Illustration in Appendix..

Cilia :: Cilia (n. pl.) Small, generally microscopic, vibrating appendages lining certain organs, as the air passages of the higher animals, and in the lower animals often covering also the whole or a part of the exterior.

Siredon :: Siredon (n.) The larval form of any salamander while it still has external gills; especially, one of those which, like the axolotl (Amblystoma Mexicanum), sometimes lay eggs while in this larval state, but which under more favorable conditions lose their gills and become normal salamanders.

Paedogenetic :: Paedogenetic (a.) Producing young while in the immature or larval state; -- said of certain insects, etc..

Gastraea :: Gastraea (n.) A primeval larval form; a double-walled sac from which, according to the hypothesis of Haeckel, man and all other animals, that in the first stages of their individual evolution pass through a two-layered structural stage, or gastrula form, must have descended. This idea constitutes the Gastraea theory of Haeckel. See Gastrula..

Longicornia :: Longicornia (n. pl.) A division of beetles, including a large number of species, in which the antennae are very long. Most of them, while in the larval state, bore into the wood or beneath the bark of trees, and some species are very destructive to fruit and shade trees. See Apple borer, under Apple, and Locust beetle, under Locust..

Acephalocyst :: Acephalocyst (n.) A larval entozoon in the form of a subglobular or oval vesicle, or hydatid, filled with fluid, sometimes found in the tissues of man and the lower animals; -- so called from the absence of a head or visible organs on the vesicle. These cysts are the immature stages of certain tapeworms. Also applied to similar cysts of different origin..

Echinococcus :: Echinococcus (n.) A parasite of man and of many domestic and wild animals, forming compound cysts or tumors (called hydatid cysts) in various organs, but especially in the liver and lungs, which often cause death. It is the larval stage of the Taenia echinococcus, a small tapeworm peculiar to the dog..

Pupiparous :: Pupiparous (a.) Bearing, or containing, a pupa; -- said of the matured larvae, or larval skins, of certain Diptera..

Anthrenus :: Anthrenus (n.) A genus of small beetles, several of which, in the larval state, are very destructive to woolen goods, fur, etc. The common museum pest is A. varius; the carpet beetle is A. scrophulariae. The larvae are commonly confounded with moths..
