Tansy Ragwort Flea Beetle

Sorry! The common name often used for species of Aulacophora (especially the orange-ish ones related to A. indica) is "pumpkin beetle" or "red pumpkin beetles". I just got here looking for actual information on those western European Longitarsus species and the identification here was just bizarre! The beetle on the picture could be Aulacophora indica, I'm just not really sure. This species group is rather difficult and there aren't any known key characters to reliably separate the females (this one is a female, based on how the antennae look like).
