In October I had beetles hatch in my house, seen on the inside of windows, attracted to sunlight. I though furniture beetle but couldn't find enough burrows to account for the >30 I had seen. Recently I noticed more beetles originating from a bag of Gardman 'Swan and Duck Food'. The pellets had lots of holes, some beetles had died but I photographed a few live ones. The food contains 'Poultry Meat, Meat & Bone Meal, Wheat, Wheatfeed, Soya, Maize, Fish Meal, Soya oil'. The beetles seem to resemble Flour Beetles but the thorax doesn't seem the correct shape, is there any other species they could be?
Did you see the reply I posted to your last message?
Struggling with website. I couldn't see my post so thought I hadn't saved it, so reposted. I just looked for your message, couldn't see then saw a species name briefly ? A.... but then it disappeared and now nowhere to be seen. Could you add the name once more please, Thank you.
I don't know if you're on facebook Nigel but Graham Finch can help you: https://www.facebook.com/groups/453937838305988/permalink/573926926307078/
He suggests these are Stegobium panacium (which I found recently too) and would like to get some specimens from you if possible?
