After a suspected 40 year absence Tansy Beetles have recently been rediscovered at Woodwalton Fen NNR in East Anglia. Natural England reported the reappearance in a press release on the 6th August 2014.
Whilst the population is believed to be small and also on water mint, this resolves concerns about the possible reintroduction to the site of beetles from the York area.
By coincidence, another web site recently posted photographs of the beetles on water mint.
Buglife have now started an ‘Adopt a Tansy Beetle‘ campaign.
