looks like a wood beetle, a little like a weevil, but with only a short proboscis, pictured crawling overa sliding door sill to the outside. Slow moving.
No interactions present.
A common pest in gardens, all the adult weevils are female and may, during the warmer months,lay several hundred eggs, without the need of a male. One of the few pests that I happily kill on sight.
Despite being unable to fly, they are dreadful pests. The grubs are white with a pale brown head, around 8-10mm long when mature. They eat roots and a 15cm pot of compost can harbour a few dozen, which make short work of any plants in the pot.
Not a native - so every reason to "remove" any that you find.
Thanks - very helpful. Perhaps sorry I let it go at the time. I will know better.
