Anal caterpillar
Anal caterpillars of Craesus septentrionalis in "frightened position"
After caterpillar is a name for the larvae of the plant wasps and the beaked flies , which resemble the caterpillars of butterflies . They only have a single free segment between the sternum and belly feet , while the caterpillars have at least two free segments.
The way of life of the anal caterpillars is quite different depending on the species. The majority of animals are free-eating, but there are also miners and gall-formers . Quite a few of them damage the foliage of trees and shrubs.
particularities
- There is only one point eye ( ocellus ) on each side of the head .
- The anal caterpillar has three pairs of breastbones and always more than five pairs of abdomen feet (butterflies only rarely).
- A number of sawfly larvae straighten up in a characteristic S-shaped curve when the "startled position" occurs.
