A larva (/ ˈ l ɑːr v ə /; pl.: larvae / ˈ l ɑːr v iː /) is a distinct juvenile form many animals undergo before metamorphosis into their next life stage. Animals with indirect development such as insects , some arachnids , amphibians , or cnidarians typically have a larval phase of their life cycle .
A trochophore (/ ˈ t r oʊ k ə ˌ f ɔːr, ˈ t r ɒ-,-k oʊ-/ [1] [2]) is a type of free-swimming planktonic marine larva with several bands of cilia. By moving their cilia rapidly, they make a water eddy to control their movement, and to bring their food closer in order to capture it more easily.
The feeding larvae of some species have been cultured for over a year and have still retained the ability to metamorphose. As the veliger stage reaches metamorphic competence, the foot becomes sufficiently developed to allow crawling on the substratum and internal development has established the organ systems necessary for juvenile life.
Blackfly Larvae from United Arab Emirates. Simulium is a genus of black flies, which may transmit diseases such as onchocerciasis (river blindness).. It is a large genus with almost 2,000 species and 38 subgenera.
Dexia rustica is a parasitic fly that uses M. melolontha larvae as their hosts. D. rustica eggs hatch underground and look for cockchafer larvae to hibernate within over the winter. Their presence will ultimately kill the beetle larvae in the spring. One to six fly larva can parasitise a single host. [6]
The larvae of the green bottle fly (Lucilia fly) are now used exclusively for this purpose, since they preferentially devour only necrotic tissue, leaving healthy tissue intact. This is an important distinction, as most other major varieties of myiasitic fly larvae attack both live and dead wound tissue indiscriminately, effectively negating ...
Leptocephalus larva. A leptocephalus (meaning "slim head" [1]) is the flat and transparent larva of the eel, marine eels, and other members of the superorder Elopomorpha.This is one of the most diverse groups of teleosts, containing 801 species in 4 orders, 24 families, and 156 genera.
The Spheciformes is a paraphyletic assemblage of insect families which collectively comprise the "sphecoid wasps".Larvae are carnivorous. These are all the members of the superfamily Apoidea which are not bees and which in older classifications were called the "Sphecoidea".
