Associated with fungi, particularly puffball mushrooms (Lycoperdaceae and related ). Inhabits the fruiting bodies of these fungi, where larvae develop and may be found.
Distribution
Recorded from Denmark, Norway, and Sweden. Distribution likely broader in northern and temperate Europe given the widespread occurrence of fungi.
Diet
Larvae and feed on fungal tissue within puffball mushrooms. Specific dietary details at the level are not well documented.
Host Associations
- Lycoperdaceae - and food sourcepuffball mushrooms
Life Cycle
Larvae develop within the fruiting bodies of puffball fungi. emerge from the fungal substrate. Specific details on -laying, larval instars, and are not well documented for most .
Ecological Role
Decomposer; contributes to the breakdown of fungal fruiting bodies, facilitating nutrient cycling in forest and grassland .
Human Relevance
Occasional nuisance when puffballs in gardens or lawns are infested. No significant economic or medical importance documented.
Similar Taxa
- DorcatomaAlso in Dorcatominae and associated with fungi; distinguished by subtle differences in antennal structure and body proportions
- Cis Ciidae (minute tree-fungus beetles); similar size and fungivorous habit but distinguished by different antennal club structure and association with bracket fungi rather than puffballs
