syrphidae eristalis larva

As the early stages of fourteen of the fifty British Syrphid genera are practically unknown, there is obviously much scope for careful and energetic field study. Similar to other saprophagous eristalines, the larvae of Eristalis Latreille, 1804 are characterized by an elongated anal segment and a telescopic breathing tube. La loro dieta si basa sull'assunzione di liquidi zuccherini e polline, perciò si nutrono essenzialmente di nettare, melatae polline. Most clips are 10-20x faster than real time. However, unlike the larva the pupa has two pairs of cornua, or horn-like bumps, located on the thorax (Metcalf 1913).
