The stilt bug Metacanthus (Cardopostethus) annulosus Fieber, 1859 is the only arachnophile cleptoparasitic true-bug in Europe, currently discovered also in Czechia. It is usually found in funnel-webs of agelenid spiders in the Mediterranean, extending to Pannonia. We encourage arachnologist for help with collecting this bug to obtain more data about its biology and ecology. |
