Biology. C. bituberculatum is considered a “synoecio-symphilic myrmecophil” which is a combination of feeding on detritus, various residuals, mildews, etc., and being fed by the ants by rendering a sweet secretion from special glands to their hosts. The species is rarely found and lives in well preserved xerothermic biotopes ( Franc 1992).

Distribution: C. bituberculatum is rare in collections and according to the Fauna Europaea database, C. bituberculatum is recorded from Austria, Bulgaria, Corsica, Croatia, Czech

Republic, France, Germany, Italy, Poland, Portugal, Slovakia, Spain, Sweden (Öland and Gotland), Switzerland, The Netherlands, Ukraine and Yugoslavia ( Vit 2021).
