Summary
Scirtidae, commonly known as marsh beetles, are a family of beetles associated primarily with aquatic environments, particularly stagnant waters. They are characterized by their multi-segmented larval antennae and are found in diverse habitats where decomposing plant material is present.
Physical Characteristics
Adults size ranges from 1.5 to 12 mm. Larval antennae are multisegmented, which distinguishes this group from other holometabolous insects.
Identification Tips
Look for multisegmented larval antennae. Marsh beetles are typically found in proximity to stagnant and flowing waters, usually near decomposing plant material.
Habitat
Larvae inhabit stagnant and flowing water, particularly rich in decomposing plant material. Adults are found on vegetation and rotting plant material along shorelines.
Distribution
Most diverse in temperate regions; in specific areas, more diverse in the eastern regions.
Diet
Larvae typically feed on decomposing plant material.
Life Cycle
Larvae may undergo as many as 11 instars during their development.
Ecosystem Role
Play a role in the decomposition process within aquatic ecosystems.
Collecting Methods
- Light traps near water bodies
- Manual collection from vegetation and decomposing plant material
Preservation Methods
- Ethanol preservation
- Drying specimens for taxonomic studies
Similar Taxa
- Elodiidae
- Helodidae
- Cyphonidae
Misconceptions
Often overlooked due to their poorly understood ecology and taxonomy.
