Thanks, it's a Livistona palm. It's never been outside and it's in the original soil that the plant came in 18 months ago. It's not like houseplant soil, it's very dense and compacted, always has been. I'm not sure whether it's possible that it's lived in there for all this time without me noticing. I've been inspecting and haven't seen it again since. Do centipedes multiply rapidly?
