Sorry, no Lemming for scale (Wikipedia tells me a Lemming is '13–18 cm (5–7 in)'. So about the same size. I would imagine there are many about, but I only notice them when they are on doorframes or something.
They happily crawl onto my hand, my coworkers tell me they are delicious grilled, so I don't mention it and go for a walk in the forest.
Southwest Cambodia
Katydid-ologist would be fun to say too
