Hi,
We just recently moved into our new place and found these bugs crawling into our living room from the patio door and molting They moved very slow and when i try to catch one, it jumped up about 12 to 18 inches straight up. I lived in Southern California and never seen an insect like this. Can you help me identify this insect, thank you.

Lawn Shrimp

Dear Jonathan,
Commonly called a Lawn Shrimp or House Hopper, this terrestrial Amphipod is not an insect, but a Crustacean.  Lawn Shrimp are native to Australia, but they have naturalized in Southern California because of the irrigated gardens that are so common.

Daniel,
Thank you for identifying the critter.  My son was so excited when I read the email you had sent and how amazed he was how a shrimp can live in our yard.  Thank you and we will be visiting the site to identify all the insects and non insects we find in our backyard and vegetable garden.   I found your site to be very educational and entertaining, thank you!
Best Regards,
Jonathan Kim

I found this bug crawling on the floor in my room. What kind of bug is this? I live in an apartment building.

Woodlouse

Woodlouse

This is a Woodlouse in the Suborder Oniscidea, and according to BugGuide, they are found:  “wherever cool, dark, moist places are available to shelter woodlice from dryness and heat during the day.”  They are generally found outdoors, or in basements, so we are guessing you are in a ground floor apartment.

Hi we would like to know what type of bug my son had in his basement bathroom. Seems to come from under the corner shower.
Thanks

Woodlice

Woodlice

Dear Flo,
These are Woodlice or Sowbugs, and children commonly call them Rollie-Pollies because they curl into balls.  They are harmless, and though they are normally found outdoors in the garden, they can sometimes be found in damp areas indoors.  Where is Davidson?

Hi,
Thanks for the response.  Davidson is between Saskatoon Saskatchewan and Regina Saskatchewan (about half way).
Is there anything we can use to get rid of them?
Thanks again,
Florence

Thanks for the clarification.  We do not provide extermination advice.

I found these little creatures in our pet’s water bowl yesterday and googled what they might be, your site gave me the answer and now I’m letting you know they are also just outside of Wilmington, NC!

Lawn Shrimp

Dear Becky,
Thanks so much for reporting this North Carolina sighting.  Lawn Shrimp are an introduced species from Australia that are well established in California, and BugGuide indicates they are also found in Florida, though the data on the site indicates Georgia reports.  This North Carolina sighting cannot be considered a normal range expansion as this is an introduced species, but there is no telling how far North they will be able to survive in North America.  We have already reported Lawn Shrimp in South Carolina.

Hi,
We found these bugs along the seawall of Stanley Park, in Vancouver, BC, Canada. They came in both brownish and grayish colours, and tended to scuttle off over the wall toward the beach / water when we got near. The only one we got a photo of was actually two bugs, with one on top of the other — they crossed the path in front of us and then went over the wall. They were 2-3 inches long. Online searches make us think they might be a kind of silverfish, but they were much larger than any I’ve ever seen domestically!

What are these hopping bugs that have come out at night under my porch light? The next morning a lot of them have died. These are in Bluffton SC .

Lawn Shrimp

Lawn Shrimp

Dear R McLain,
This looks and acts like a Lawn Shrimp or House Hopper,
Arcitalitrus sylvaticus, a species described on BugGuide as being from “Southeastern Australia (New South Wales and Victoria), as well as nearby areas of the Pacific, but introduced into New Zealand, the British Isles, Florida and California” and preferring habitat that is “Moist soil and organic matter within 13 mm of the surface, often among ivy or other ground covers, mostly eucalyptus. Their exoskelton has no waxy coating to keep moisture in, so they can’t survive dryness. They drown in water, though, so they need continuously moist, but not waterlogged conditions.”  Based on this BugGuide posting, they are spreading from Florida to nearby Georgia and your posting indicates they have now spread north to South Carolina.

Thank you Daniel.  I thought they resembled shrimp!

Lawn Shrimp and true Shrimp are classified together as Crustaceans in the same subphylum.
