I emptied the water out of a large bowl I had left outside the other day, but since it rained again yesterday I went to empty it again today and found about ten of these baby shrimp in the bowl. I live about 5 miles from Mobile Bay, but I still thought that was kind of weird… then I found your page and concluded they might be lawn shrimp. The antennae fell off before I took the picture.
You are correct that this is a terrestrial amphipod known as a Lawn Shrimp. They are also known as House Hoppers because they sometimes enter homes in large numbers after a rain. Lawn Shrimp are native to Australia, but they have been introduced to North America, and most of our reports come from California. We have also gotten reports from Florida, but we believe your account from Alabama is a first for us. Lawn Shrimp can proliferate in great numbers in gardens, but they are generally not noticed until it rains and they enter homes where they quickly die.
