What they do
Adult soldier flies often feed at flowers and can help move pollen between plants.

Family Stratiomyidae
Many adults visit flowers for nectar and can move pollen between blooms while feeding.

Key takeaways
A quick summary you can scan in under 10 seconds.
Adult soldier flies often feed at flowers and can help move pollen between plants.
A steady sequence of blooms plus “messy” natural areas for their life stages (like leaf litter and damp organic material).
Plant a mix of native, open-flowered plants so something is blooming from early season through fall.
Why it matters
Key Impacts
Identification
Often seen resting or feeding on flowers in full sun.
Many have a somewhat flattened or elongated body with a neat, "armored" look.
Some species show yellow-and-black patterning that can resemble wasps (mimicry varies).
Wings are typically clear or lightly tinted; when at rest, they may be held flat over the back.




Range and habitat
Life cycle
Like all flies, soldier flies go through complete metamorphosis (egg → larva → pupa → adult). Adults are the stage you’ll most often see on flowers, while larvae typically develop out of sight in habitat that provides moisture and organic material (exact needs vary by species).
Adults begin appearing as temperatures warm and early flowers open (timing varies by region). Early blooms can be important for the first active adults.
Many sightings occur when gardens and meadows are in full bloom. Adults feed, mate, and lay eggs; larvae develop in suitable habitat nearby.
Some species remain active as long as flowers are available. Late-blooming plants can extend feeding opportunities.
Many species persist in protected life stages (often as larvae or pupae) in sheltered microhabitats.
Gardening guide
Provide the right food and habitat to help this pollinator thrive.
Early season
Mid-season
Late season
Leave some leaf litter under shrubs or in a designated garden corner.
Keep a small patch of undisturbed soil or mulch where moisture can remain stable.
Add native grasses and dense plantings to create humid, sheltered microclimates.
Maintain wetland-friendly edges if you have them (pond margins, rain gardens, swales).
Compost thoughtfully: keep it covered/contained if needed, but allow natural decomposition processes.
Habitat loss and fragmentation that remove flower-rich areas and damp, organic microhabitats.
Pesticides, including systemic pesticides (gets inside the plant), which can contaminate nectar and pollen.
Broad insecticide use for "pest control" that also kills beneficial insects.
Bloom gaps where landscapes have only spring flowers (or only a short burst of bloom).
Over-tidying (removing leaf litter, dead stems, and natural debris) that reduces life-stage shelter.
Take action
Plant for continuous bloom: include early, mid, and late-season native flowers (aim for variety in flower shapes).
Skip pesticides: choose non-chemical options first, and avoid systemic products that get inside the plant.
Keep a "life-stage corner": leave some leaf litter, stems, and a bit of undisturbed ground or mulch.
Add moisture-smart habitat: rain gardens, native plantings near downspouts, or pond-edge plantings where appropriate.
Student challenge
Do a 10-minute "flower visitor survey" on two different days—count how many different kinds of flies you see on flowers and note which blooms they prefer.
Examples
Examples from this subgroup. Status varies by region.
Hermetia illucens
This is a well-known soldier fly, and adults may visit flowers while feeding on nectar. It’s also a useful example of how fly life stages can depend on organic material and sheltered habitat.
Chloromyia formosa
This species is often noted as a flower visitor, showing how soldier flies can be regular participants in pollination. Its presence can be a sign that a landscape has both blooms and suitable nearby habitat.
Odontomyia spp.
Several Odontomyia species are associated with wetter habitats, and adults may visit flowers along edges and openings. They highlight the value of wetland-friendly plantings and naturalized water features for pollinator diversity.
