Lawn Shrimp

Dear Fernando,
These are terrestrial Amphipods commonly called Lawn Shrimp or Househoppers, and they are an invasive species introduced from Australia.  According to BugGuide:  “
These are rarely seen except when flooding or lack of moisture forces them to abandon their home in the soil in search for suitable conditions. At such times they often end up dieing on pavement or in homes and become a nuisance. Once they start appearing, there’s not much that can be done except to sweep them up- pesticides are pointless, bcause by then they’re already dying or dead.  The best solution is to keep the numbers down the rest of the year by keeping the soil from staying too moist- in California, especially, they’re a sign of overwatering. Physical barriers like weather-stripping can also help to keep them out of homes, but their bodies are flat and narrow, allowing them to slip through surprisingly narrow cracks.  Non-native; introduced probably from Australia along with blue-gum eucalyptus trees in the 1800s. First recorded in San Francisco, CA in 1967.

Daniel, thank you very much for the information , indeed they look like small shrimp!!!!
I greatly appreciate your time.
Regards.
Fernando

Saw these mating….what ever they are…. along the inlet area of Beaufort, S.C.
I have looked in all my bug books and I can’t find anything like them. Can you tell me what they are?
Thanks

Mating Warf Roaches

Dear Janet,
Your image is awesome.  Though they are sometimes called Warf Roaches, these are actually Marine Isopods, a type of Crustacean related to the terrestrial Wood Louse.  We are confident that we have correctly identified your mating Warf Roaches as
Ligia exotica thanks to BugGuide where the range is listed as:  “Atlantic coast NJ south to Florida.”

Hi
Every summer I get these in my room. I have a wall a.c. unit. I always think this is the way they get in but then I find them coming out from under my bed. I live in Florida. I thought I got rid of them but I guess it was the cooler months. I need help.

Subject: The wall walking bug
Location: Belgium, Gent

Hello,
After a more general cleaning of my home, the next day I noticed this bug walking on the wall. It might have come out of the wooden beams(I live in the last floor, roof floor kind of an attic). It seemed to be intelligent because it moved only when I was gone. I took a picture while it was there. To take in account, our house has damp problems, but apart from that we try to keep it as clean and as dry as possible. There is not much light in the room in general. This bug was around 1cm long, it was the last days of April when I saw it.
Thank you so much for the great work that you do, I will be looking forward on an answer to hopefully receive an answer for what kind of bug this might be!

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. ”
