Carlisis wahlbergi (Stål, 1858) aka the Gardenia twig wilter is a Central and Southern African species of Coreidae in the order Hemiptera.

[2] The species shows a marked preference for the sap of Gardenia thunbergia and Gardenia volkensii, and its nymphs possess powerfully offensive scent glands to discourage predation or interference.

This defensive secretion has been analysed and found to consist largely of acetic acid (66%), trans-2-hexenal (17%) and 3-hydroxybutanal (14%).

[4] Nymphs of various Coreids secrete alarm pheromones from the dorsal abdominal glands.

The genus Carlisis comprises 4 species:[5][6] This Coreoidea article is a stub.
