Solenopsis
An identification with real consequences.
Recognize the limits of a fire-ant label and check official movement guidance.
Imported fire-ant risk and identification context; not an acquisition or captive-founding guide.

The UF/IFAS account distinguishes imported S. invicta from other fire ants. Worker variation and queen social forms make a simple size or color rule unreliable. A genus label is not enough to establish either species or legal status.

In your setup
Photograph from a safe distance and seek regional identification. Avoid disturbing suspected fire-ant nests or handling workers and queens. This page does not recommend collecting or acquiring imported fire ants.
Check current restrictions before movement
USDA APHIS maintains an imported-fire-ant quarantine program covering regulated articles from affected areas. Boundaries and movement requirements can change; this is not a worldwide ban on every Solenopsis.

In your setup
Use the current official guidance rather than an old state list. Do not transport soil, plants or nest material from a suspected infestation without the appropriate advice. Keep existing captive ants contained; do not release them.
An observation is useful without collection
The species account discusses flights in relation to suitable weather. It does not establish a guaranteed flight date at your location.

In your setup
Report the observation type, local date, approximate area and identification confidence. Leave the species uncertain if necessary. A map report is not permission to collect, transport or release ants.
Build a record for this colony
In your setup
Log dated food responses, reservoir and containment checks, and worker and brood estimates. Mark estimates as estimates and leave unknown facts blank. These notes do not fill in or alter your saved colony profile.
Before acquiring or moving ants
Consult the library’s movement guidance and official sources and the authorities relevant to your location.
