Dear Justin,
There is not much left of this Silverfish, a common household pest that will eat most anything organic, including the glue in book bindings.

I’ve seen a few of these alive in my bathroom sink. They seem to be coming up from the drain. They are fast-moving, and this one is about 1.5″ long. I live in the San Mateo hills south of San Francisco, and we are on a septic system here. These bugs have been spotted in September and October.

Bristletail

Dear Adam,
Based on this BugGuide image, we are confident that this is a primitive insect in the order Microcoryphia, known as a Bristletail.  According to BugGuide:  “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” and their food is “algae, lichen, moss, decaying vegetation; usually feed at night.”

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.
Best.

These bugs are common in my house. They look like little crustaceans and they can jump and are tough. What is this bug??

Terrestrial Amphipod, possibly

Jumping Bristletail

Dear Arianna,
This one has us a bit stumped.  We are pretty sure it is not a Silverfish, which is pictured on BugGuide.  Furthermore, Silverfish do not jump and they are not tough.  They practically disintegrate when smashed.  This looks more like a Crustacean, and it appears to be a Terrestrial Amphipod, but it does not appear to be a Lawn Shrimp or House Hopper, a usual suspect.  Perhaps one of our readers will have a better idea.  How close are you to the shore?  Where in Southern California are you located?

Correction:  Thanks to Juliet who quickly directed us to Jumping Bristletails on Wikipedia.  We found this matching image on BugGuide.  According to BugGuide:  “short lateral styli (rudimentary appendages) on abdominal segments 2-9; able to jump up to 10 cm by snapping abdomen against ground.”  It was those lateral styli that led us to question if this might be a crustacean.
