Tropisternus lateralis is a species of hydrophilid beetle that ranges across much of the Americas.[1]
Description
[edit]
Adult T. lateralis nimabatus, the subspecies found in the eastern United States, are distinguished by having uniformly dark elytra and pronotum with light-colored borders.[1]
Distribution
[edit]The range of T. lateralis includes North America as far north as southern Canada, South America south to northern Chile and Argentina, the Caribbean, and the Galápagos Islands.[1][2] T. lateralis humeralis has been accidentally introduced to Oahu.[3]
Behavior
[edit]
T. lateralis exhibits stridulation during stress, calling, and courtship.[4] Eggs are deposited in cases under water, and larvae are fully aquatic. While adults are primarily aquatic, they breathe air and can fly.[1] Adult T. lateralis avoid colonizing and laying egg cases in ponds that contain fish, which are potential predators of all life stages of the beetles.[5]
Subspecies
[edit]There are five recognized subspecies of Tropisternus lateralis.[6]
- T. lateralis humeralis Motschulsky, 1850
- T. lateralis lateralis (Fabricius, 1775)
- T. lateralis limbalis (LeConte, 1855)
- T. lateralis limbatus (Brullé, 1837)
- T. lateralis nimbatus (Say, 1823)
