Arcitalitrus sylvaticus
lawn shrimp, lawn prawn, landhopper
Arcitalitrus sylvaticus is a terrestrial amphipod native to Australia and nearby Pacific regions. It has been introduced to California, New Zealand, North Carolina, and Florida, with the first California record in 1967. The species is highly sensitive to moisture conditions, perishing in dry environments and drowning in saturated soils. It serves as a significant primary decomposer of leaf litter in its habitat.
