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.

Bristletail

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.

I’ve found a few of these bugs in my house in Thailand. Striped body is around 1-2cm long. Mostly seen in rainy season. Mostly seen on the floor, but also saw one halfway up a wall. Can you tell me what these are???

I found this in our bathroom. It comes out of the wooden floor in the night… Probably also likes wather. Can you please tell me what it is and how to get rid of it ? There are many of them small and big (3-5).

Hi there! I’m from Windsor, ON Canada and for a while now I have been seeing these small bugs coming in and out from underneith the moldings of my bathroom wall. I never see them during the day but I work midnights so when I get home and I open the light to the bathroom there it is! It sees the light and scurries back into the cracks. The house is only 3 years old and I’m thinking they’re just visiting from outside because the only place I see them coming from is the one bathroom wall that faces the outside. Haven’t come across them elsewhere in the house. What are these bugs? They’re very small and you can’t even tell they have legs unless you look very close so they just look like a very fast baby worm wiggling away. You can get a better look at the colours and shape of it from the photo I will provide. Thanks!

Dear Sonia,
This is a primitive insect known as a Silverfish, and they are common household pests.  According to BugGuide:  “often found indoors in damp environments; the Common Silverfish is frequently seen in bathrooms and kitchens, whereas the Firebrat is usually found in basements around furnaces and in insulation around hot water and heating pipes; these and other species also occur outdoors under bark, in leaf litter, caves, ant nests, deserts, etc.”  They have plenty to eat indoors.  According to BugGuide, they are:  “omnivorous: starchy foods, cereals, moist wheat flour, glue on book bindings and wallpaper, starch in clothing made of cotton or rayon fabric.”

I’ve been finding these bugs in my bathroom and anywhere that moisture is. Like the kitchen sink or in drying dishes. They are very quick bugs and move so fast!
Do you know what they are?
