About Libelloides coccajus (Denis & Schiffermüller), 1775
Adult Libelloides coccajus reach 25 millimetres (0.98 in) in body length, with a wingspan of 45–55 millimetres (1.8–2.2 in). Their body is black and quite hairy, with large bulging eyes and long, clubbed antennae. Their wings are not covered in scales, are partly transparent, and feature bright yellow regions in the first third, with dark brown colouring on the outer portion. An elongated black marking is present near the end of the posterior wing edge, and the wing venation is black. At rest, these insects hold their wings spread, just like dragonflies. This species is quite similar in appearance to Libelloides lacteus. This rare owlfly is found in France, the Czech Republic, Germany, Italy, Spain and Switzerland. Libelloides coccajus mainly inhabits areas with tall grass and sunny rocky slopes, at elevations up to 1,500 metres (4,900 ft) above sea level. Sightings have been recorded at elevations up to 1,800 metres (5,900 ft) on the French/Italian border in the high Susa Valley.
