Erotylinae
Erotylinae is a subfamily of beetles belonging to the family Erotylidae, also known as the pleasing fungus beetles. Erotylinae is one of several subfamilies within Erotylidae, and its members can be distinguished by a combination of morphological characteristics.
Characteristics:
Members of the Erotylinae subfamily are typically characterized by:
- Body Shape: Often oval or elongate-oval in shape, typically somewhat flattened.
- Coloration: Frequently brightly colored, with patterns of red, orange, yellow, black, or metallic hues. This bright coloration is thought to be aposematic, warning predators of their potential toxicity.
- Antennae: Clubbed antennae, with the terminal segments broadened and forming a distinct club. The shape of the antennal club is a key diagnostic feature for differentiating various species and genera.
- Tarsi: Tarsi are typically 5-5-5, meaning that both males and females have five tarsal segments on each leg.
- Habitat: Found in association with fungi, decaying wood, or vegetation where fungi are present.
Ecology:
Erotylinae beetles are primarily fungivores, meaning their larvae and adults feed on fungi. They can be found on various types of fungi, including shelf fungi, mushrooms, and slime molds. Some species may also feed on decaying plant matter or pollen.
Taxonomy:
The classification within Erotylidae and Erotylinae can be complex and subject to revision as new research emerges. Genera within Erotylinae are differentiated by subtle morphological differences, particularly in the antennal club, pronotal structure, and elytral features. The exact number of genera and species within the subfamily is not precisely defined due to ongoing taxonomic work.
Distribution:
Erotylinae beetles have a global distribution, with species found in various habitats across different continents, including tropical, subtropical, and temperate regions. Their distribution is closely linked to the availability of their fungal food sources.
