Flea Beetle - Longitarsus jacobaeae? 2
Red Flea Beetle - possibly Tansy Ragwort Flea Beetle - Longitarsus jacobaeae or similar. Thanks, Boris, for the ID. I'm mildly disappointed it's not my first ID attempt - Neocrepidodera ferruginea as there are plenty of other pictures of the Tansy Ragwort Flea Beetle out there.
