Where and when are you looking?
mi
Radius is yours to set (roughly 1–310 mi / 1–500 km). Use a ZIP/postal code in supported countries, or an island, town, or settlement in the Bahamas. Anywhere else can be selected directly on the map. Coverage and precision vary by country.
Saved places and email alerts
Email alerts that work while you are away
We check the full 7-day forecast automatically several times a day and email as soon as a forecast day reaches your threshold. The email includes the predicted date and lead time without repeating the same date. Confirm the first email to activate it; every alert can be unsubscribed. A species name is carried as a watch target, while the email trigger itself uses the weather score.

70–100 Prime collecting
— good rain of at least 0.50 in during the recent window (45pts) + high temperature in range (33pts) + calm wind (22pts). Ordinary species observations do not add gauge points.
Status:Unlikelyconditions or seasonal timing are weak
Possiblepublished flight month, or season and weather reasonably align
Primecore-model peak timing and all 3 checks align
— ●peak = documented peak-activity month
Confidence:Highercore model includes seasonal and weather checks
Moderatepublished flight month without species-specific weather thresholds
— confidence describes evidence detail, not a guaranteed flight
Regional window:Baseline northern-season months— latitude and hemisphere adjustments are estimates and are shown in each evidence explanation
Presence evidence:nearby observations confirm that a species occurs locally
— one lifetime nearby record lowers the species by one status level; observation counts never raise status or change the weather gauge
Flight evidence:queen, alate, or observed-flight records belong in the Personal Field Log
— ordinary observations may be workers and are never treated as evidence of an imminent nuptial flight

Nearby ant observations
From live iNaturalist observations within your search radius. These records confirm presence only and may represent workers; their abundance and recency are not used as flight evidence. Species outside the curated flight-timing database are labeled observation only; no unsupported flight prediction is made for them.
