What interesting bug did I see at 4000m/13000ft altitude on rocks in the Swiss alps? The pic is of the back end of the bug as it was very quick to get away. It jumped with a distinctive flicking motion in which it arched it’s back up and down. Reminiscent of a shrimp and silverfish. Pic taken at midday on 29th July 2016, in sunshine, air temperature probably 5 degrees C.

Jumping Bristletail

Dear Ash,
We believe this is a Jumping Bristletail in the family Machilidae, a group of insects that are quite similar to Silverfish.  According to BugGuide, a North American site, the habitat is:  “outdoor grassy or wooded environments: under bark, in leaf litter, rock crevices, or under stones; not normally found in homes, does not breed indoors, and not considered a pest.”  Here is a very similar looking image from Alamy

Awesome! Thank you so much for your story response.
