Summary
Leiodinae is a diverse subfamily of round fungus beetles with over 1,800 described species in approximately 70 genera, primarily found in association with fungi.
Physical Characteristics
Leiodinae are small to medium-sized beetles with a rounded or oval body shape. Their coloration can vary, often presenting dull hues, including browns and blacks, adapted for camouflage among fungi and leaf litter.
Identification Tips
Look for their rounded bodies and the habitat they inhabit, which is usually associated with fungus. The presence of soft, often hairless bodies can also help in identification.
Habitat
Leiodinae primarily inhabit forested areas, particularly in environments where fungal growth is prevalent, such as decaying wood, leaf litter, and under bark.
Distribution
This subfamily has a worldwide distribution, with species found in various ecosystems ranging from temperate to tropical regions.
Diet
The diet of Leiodinae generally consists of fungi, particularly decaying mushrooms and other decomposing organic material.
Life Cycle
The life cycle typically involves larval stages that develop within or near their fungal food sources, although specific details can vary among genera.
Reproduction
Reproduction usually occurs on or near fungal substrates, with females laying eggs in areas that offer food for the larvae upon hatching.
Predators
Predators of Leiodinae may include various insectivorous mammals, birds, and other predatory insects that rely on beetles as a food source.
Ecosystem Role
Leiodinae play a significant role in decomposition and nutrient cycling by breaking down fungi and organic matter in forest ecosystems.
Collecting Methods
- Pitfall traps
- Hand collecting under logs
- Sweep netting near fungal growths
Preservation Methods
- Ethanol preservation
- Pinning and drying specimens
Evolution
The Leiodinae subfamily is part of a long evolutionary lineage within the order Coleoptera, indicating a diversified adaptive history related to fungal consumption.
Similar Taxa
Misconceptions
There is often confusion between Leiodinae and other small beetles due to their similar appearance, especially those that also inhabit decomposing materials.
