Strudiella devonica |
||||||||
Strudiella devonica is an arthropod from the Famennium (Upper Devonian) of Belgium, interpretedas a flying insect in its first description . In contrast to the oldest insect Rhyniognatha from the Pragium (Lower Devonian ), Strudiella has been preserved more completely. The interpretation as an insect is very controversial.
description
Strudiella had triangular mouthparts and two antennae on the head. The abdomen consisted of ten segments . Strudiella also had six legs, but this is what Hörnschemeyer et al. 2013 no. As with all insects, there were two large compound eyes on the head . However, since no fully grown animal ( imago ) was found, but only the nymph (youth stage), it is unclear whether Strudiella had wings.
As a nymph, Strudiella was eight millimeters long and 1.7 millimeters wide.
Way of life
Like dragonfly nymphs , Strudiella most likely lived in the water as a nymph. The streamlined body also suggests that Strudiella was a water dweller. Similar to dragonfly larvae, Strudiella will have eaten other small aquatic animals.
