Dried Fruit Beetle Carpophilus hemipterus
This came to sugar. I took three photos, two of which weren't in focus, and then it flew. Sadly I wasn't able to relocate it, so only had these three poor photos to go on to identify it and no specimen. I saw that the elytra fell well short of the tip of the abdomen and this made me wonder if it was a strange rove beetle, but my attempts to find something that looked like this came to nought, and the beetle seemed destined to never be identified.
In 2026, while identifying a weevil caught on the same day, I came across the photos again, and this time with a few more years' experience I recognised that it was not a rove beetle. It reminded me of Nitidulidae and a bit of research led to Carophilus, and unless I'm overlooking something, the only contender with this distinctive elytral pattern is hemipterus.
