In wet rot of decaying branch. when exposed, initially tried to burrow away, then "played dead", and finally burrowed away into a softer part of the timber
Hi mahargiani. These look like two different beetles. Photo one is of a pie dish beetle but there is not enough detail to ID. The last three photos are of a different beetle. Could you please remove the 1st photo. Thanks
Done. It was obvious as soon as you pointed it out! Unfortunately I only have the one photo of the pie dish beetle, might try looking for one next time I'm in that location.
