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

Subject: Weird insect in NC Linville Gorge
Location: 3050 ft, Shortoff Mountain, Linville Gorge Wilderness, North Carolina.

My name is Tyler Goulet. I am in “The Linville Gorge Facebook Group”. One of the members posted a picture and video of what I believe to be some sort of nymph. My friend is a fly fisherman who has taught me a little. Yet even he can’t identify it. We believe it may have been carried in by a bird. The insect was found in the pond on Shortoff Mountain in the Linville Gorge Wilderness. Which is 3050 ft in elevation.
Attached are two pictures of the insect. One in someones hands, it located closer to the edge of water near his thumb and index finger on the left hand. Also a screenshot of the gps coordinates.
Thank you in advance for your services

Fairy Shrimp

Dear Tyler,
This appears to be the aquatic nymph or naiad of a Damselfly.  Adults Damselflies are winged and they will frequently lay eggs in temporary ponds.

Correction:  Fairy Shrimp
Thanks to a comment from Black Zarak, we took a closer look and we are inclined to agree that this is a Fairy Shrimp.  The quality of the image is not great, but upon extreme magnification we are able to make out the swimming appendages.  This reminds us that with all the rain we have experienced in Los Angeles the past week, Fairy Shrimp may be hatching in the Rio de Los Angeles State Park in the Cypress Park neighborhood of Los Angeles.

Thank you for the reply.    The group also agreed that it is a fairy shrimp.    But I can’t find any information that would say they’re native to North Carolina.     I could only find states like Oregon, California and Arizona.     Thank you so much again.

Good morning Tyler,
During the 1960s, our editorial staff remembers caught Fairy Shrimp from the order Anostraca in Ohio in seasonal, vernal ponds that dried out in the summer.  BugGuide has data on sightings from nearby Georgia, Kentucky and Massachusetts, but the lack of reports from North Carolina just means no images have been posted from that state.  The Vernal Pools site has some nice information on Fairy Shrimp in Massachusetts and contains this statement:  “Winter eggs can be carried from pools to pool by traveling animals, or, in the case of pools that dry out completely, picked up in the wind and be blown to other pools. For reasons currently unknown to scientists, there is an uneven level of population in a pool from year to year. In a single pool, fairy shrimp may be abundant for several consecutive years and absent the next.”  The Pennsylvania Natural Heritage Program site states:  “Two species of fairy shrimp found in Pennsylvania are the eastern fairy shrimp (
Eubranchipus holmani) and the springtime fairy shrimp (E. vernalis). The most frequently encountered species in Pennsylvania is the springtime fairy shrimp. E. vernalis has straight, smooth antennae, while E. holmani has longer antennae with medial serrations. The image to the right is a close-up view of male Eubranchipus vernalis second antennae. ”

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

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.

Came across this critter flipped over, struggling at the edge of a creek. Managed to take this photo of the ventral side, but some kids crushed it with a rock before I could turn it over. It was quite big, four or five inches at least, large enough that I could have cradled it in my hand. Looking at photo, it appears to have eight legs, but spiders in this region are not normally this big or robust, so my guess is that it was a crayfish and that the other limbs are not apparent in the photo and/or were pulled off by something.

Crayfish and Fly

Crayfish and Fly

Dear Anonymous in Indianapolis,
This is most definitely a Crayfish (Crawfish, Clawfish or Crawdad) and it appears to be missing its claws or more correctly, its Chelipeds.  Though it is not very distinctive, we are curious about the identity of the Fly in the upper right corner of your image.  We hope we never hear again about the kids who crushed it.
