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.

    Isn’t it a bristletail?

    “The Archaeognatha are an order of wingless insects, also known as jumping bristletails.”
