Neophyllomyza
Melander, 1913
A of small flies in the Milichiidae, commonly known as freeloader flies. The Nearctic fauna comprises two : N. quadricornis and N. gaulti. Both species are saproxylic, with larvae developing in decaying wood of hardwood trees. are associated with decaying logs and show distinct temporal and ecological partitioning despite sympatric distributions.

Habitat
Decaying wood of hardwood trees, specifically sugar maple (Acer saccharum) and American beech (Fagus grandifolia). N. quadricornis occurs in logs at both early and advanced decay stages; N. gaulti is found almost exclusively in advanced decay stages.
Distribution
Eastern Canada. Records also indicate presence in northern Europe (Sweden, Norway).
Seasonality
N. quadricornis: late May through September, with peak in late June. N. gaulti: mid-July to mid-August.
Host Associations
- Acer saccharum - larval decaying logs
- Fagus grandifolia - larval decaying logs
Life Cycle
Larvae are saproxylic, developing within decaying tree trunks. emerge from logs; exact larval food source within decaying wood is unknown.
Behavior
of both have been observed as freeloaders at -tended colonies, where they feed on honeydew. The two Nearctic species exhibit partitioning by wood decomposition stage and , potentially reducing despite shared larval resources.
Ecological Role
Saproxylic decomposer in forest . Contributes to nutrient cycling in decaying hardwood logs.
