Strudiella devonica is a possible insect fossil, the first complete Late Devonian insect, probably terrestrial. It was recovered in the Strud (Gesves, Belgium) environment from the Bois des Mouches Formation, Upper Famennian. It had unspecialized, 'orthopteroid', mouthparts, indicating an omnivorous diet.
This discovery reduces a previous gap of 45 million years in the evolutionary history of insects, part of the arthropod gap (the 'gap' still occurs in the early Carboniferous, coinciding and extending past the Romer's gap for tetrapods, which may have been caused by low oxygen levels in the atmosphere).[2] Body segments, legs and antennae are visible; however, genitalia were not preserved. The insect has no wings, but it may be a juvenile.
