Summary

Erotylidae, or pleasing fungus beetles, is a diverse family of beetles that primarily feed on fungi associated with decaying wood. They play important roles in their ecosystems but vary in their impacts on human interests, ranging from beneficial to negligible.

Physical Characteristics

Size ranges from 2 to 22 mm, exhibiting various colors among different species; typically oval or elongated body shapes.

Identification Tips

Distinguished by their association with fungi and often found near decaying wood. They belong to multiple tribes and subfamilies, and identification may require keying out based on specific morphological traits.

Habitat

Predominantly found in environments where decaying wood and fungi are present; most diverse in warmer climates, particularly in tropical regions.

Distribution

Worldwide, with notable presence in North America except for far northern areas; diversity peaks in tropical climates.

Diet

Adults and larvae feed on fruiting bodies of fungi, thriving particularly in decaying wood.

Life Cycle

Life stages include egg, larva, pupa, and adult; typically, larvae feed on fungal mycelium or fruiting bodies, contributing to their development.

Reproduction

Details on specific reproductive methods are not provided, but like most beetles, reproduction likely involves mating and egg-laying in habitats conducive to larval development.

Ecosystem Role

Plays a role in the decomposition of wood and organic matter via their feeding on fungi, facilitating nutrient cycling.

Economic Impact

Some species are considered pests, while others may serve as important pollinators for certain plants, such as cycads; generally, they are of little economic significance.

Health Concerns

Most species are inoffensive and pose little threat to human health.

Collecting Methods

Hand collecting in habitats with decaying wood and fungi
Traps baited with attractive fungi

Preservation Methods

Ethanol preservation
Dry-preservation for mounted specimens

Evolution

The family Erotylidae has seen taxonomic revisions, with ongoing debates about the monophyly of some subfamilies and tribes within it; further phylogenetic studies are anticipated.
