Common frog (Rana temporaria) tadpole. A tadpole or polliwog (also spelled pollywog) is the larval stage in the biological life cycle of an amphibian.Most tadpoles are fully aquatic, though some species of amphibians have tadpoles that are terrestrial.
Aquatic macroinvertebrates are insects in their nymph and larval stages, snails, worms, crayfish, and clams that spend at least part of their lives in water. These insects play a large role in freshwater ecosystems by recycling nutrients as well as providing food to higher trophic levels.
Larva of the Papilio xuthus butterfly Eurosta solidaginis goldenrod gall fly larva. 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.
The pupal stage may last weeks, months, or even years, depending on temperature and the species of insect. [3] [4] For example, the pupal stage lasts eight to fifteen days in monarch butterflies. [5] The pupa may enter dormancy or diapause until the appropriate season to emerge as an adult insect.

Pupae complete their development in two to six days at 35 °C (95 °F), but may take 20 days or more at 14 °C (57 °F). [14] When metamorphosis is complete, the adult housefly emerges from the pupa. To do this, it uses the ptilinum, an eversible pouch on its head, to tear open the end of the pupal case. Having emerged from the pupa, it ceases ...

Pupa. Variable in form but most often curved backwards. It is angulate, with the head truncate or rounded and the back of abdomen is smooth or tuberculate. It is attached by the tail, normally in a perpendicular position, and further secured by a silken girth round the middle. In Parnassius, the pupa is placed in a loose silken web between leaves.
