Morphological description

Oedipoda careulescens is a medium-sized grasshopper, between 15 and 21 mm for males and between 22 to 28 mm for females. The body coloration varies greatly depending on the substrate on which the animals have developed: reddish brown, gray, yellowish, or even completely dark or bright. The forewings are crossed most often by two or three pale bands, but the most striking characteristic, very visible when the insect flies away, is the bright coloration of the hind wings, a beautiful turquoise highlighted with a black marginal stripe. Furthermore, the posterior femora have a notch on their upper surface. At rest, confusion is possible with other Oedipoda species such as O. germanica

Ecology

Oedipoda caerulescens frequents dry areas with low and open vegetation: dunes, heathlands, grasslands on sand and sunlit limestone rocks. Many stations correspond to land recently used for human activities, such as coal spoil heaps, quarries and pits, the ballast of railway tracks, etc. It is exclusively a terrestrial insect, and its cryptic coloration often matches its substrate. The female lays her eggs in bare, dry soil. In this species, acoustic emissions are virtually nonexistent. The diet consists mainly of grasses.
