Nylanderia
A small ant. A careful identification.
Know the limits of a crazy-ant label before choosing a feeding, heating or seasonal routine.
Genus-level identification guidance, with N. bourbonica as a clearly labeled species example.

Nylanderia contains many species, and similar worker appearances can make identification difficult. A common name or fast movement is not enough to select a species or infer whether a colony is native.

In your setup
Keep a genus-level label when that is all you know. For identification, preserve the observation date, general geographic origin and clear photos with a scale. Avoid publishing a precise collection address.
Use species examples carefully
UF/IFAS describes N. bourbonica as a generalist omnivore using insects for protein and sugary resources for carbohydrates. That is a species example, not proof of an identical diet or schedule for every Nylanderia colony.

In your setup
For a worker colony, watch actual feeding response and choose portions that can be managed without trapping workers. Keep drinking water available, inspect enclosure gaps and remove spoiled leftovers with minimal disturbance.
Leave unsupported targets open
UF/IFAS reports warm-weather, early-morning or post-rain flights for N. bourbonica. That example is a reason to avoid assigning a single spring-flight calendar to the genus.

In your setup
Do not assign queen number, founding method, flight months or a winter-rest protocol from Nylanderia alone. Confirm the species and origin before choosing environmental targets. Record what your colony does rather than filling gaps with a different species’ numbers.
Check before collecting or moving
UF/IFAS describes N. bourbonica as introduced to the New World. That species example does not identify the origin or legal status of your colony. Resolve identification and movement requirements with the relevant authorities before acquisition or transport.

In your setup
Use local identification expertise and the relevant official authorities. Keep an existing captive colony contained while you seek guidance; do not release it outdoors.
Let observations tell the story
In your setup
Log food response, escape or condensation checks and worker/brood estimates with dates. Leave unknown species, origin and counts blank in the colony profile. This guide supplies context, not measurements about your own colony.
Before acquiring or moving ants
Consult the library’s movement guidance and official sources and the authorities relevant to your location.
