Lawn Shrimp

Dear Becky,
You have Lawn Shrimp, also known as House Hoppers.  They are introduced terrestrial Amphipods from Australia that have naturalized in California, and have also been reported in Georgia, according to BugGuide, but this is the first report we know of from Texas.  According to BugGuide their habitat 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.”  BugGuide also notes:  “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.”

Lawn Shrimp

Dear Simon,
You are correct that this Terrestrial Amphipod, commonly called a Lawn Shrimp or House Hopper, is from oversees, however, we do not believe it came from your boxes.  Lawn Shrimp have been reported in Southern California for many years.  According to BugGuide, their range is “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 “Non-native; introduced probably from Australia along with blue-gum eucalyptus trees in the 1800s. First recorded in San Francisco, CA in 1967.”  They are not usually noticed until we have soaking rains and they seek shelter from the water-soaked ground.  BugGuide notes:  “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.”
