Ants swarm during nuptial flights — brief mating events that most species time to warm, humid days, often within hours of rain from late spring through early autumn. The exact day varies by species and region, so there is no fixed calendar. Dealate forecasts these windows species by species, scoring each day's likelihood and the best hours to look up, rather than promising a date it cannot know.

A nuptial flight is the brief window when a colony's winged queens and males (alates) leave the nest to mate on the wing — the only time most ants fly. It lasts hours, not days, and depends on weather triggers, so missing it can mean waiting until next year. Dealate forecasts nuptial flights species by species, with the day's best window and a rolling 7-day outlook, to help you be outside at the right moment.

A dealate is an ant — usually a newly mated queen — that has shed its wings after a nuptial flight, snapping them off to begin founding a colony on the ground. The word, and the app's name, marks the moment a flight ends and a new colony begins. Dealate, the ant nuptial-flight forecast app, is named for this transition and helps ant keepers and naturalists find queens during the flights that produce them.

Nuptial flights are triggered by a combination of weather cues — commonly warmth, high humidity, and rainfall that softens the ground, along with low wind and the right season. Different ant species respond to different thresholds, so conditions that launch one species may not move another. Dealate builds its forecast from temperature, humidity, rainfall, and wind, but these are probabilistic triggers, not switches: the same weather does not guarantee a flight.

Dealate's forecast is a probability, not a promise. Dealate scores each ant species' likelihood of flying from published weather thresholds and a rolling 7-day outlook, but nuptial flights depend on local triggers no model fully captures — so treat a high score as a strong reason to look up, not a guarantee. Logged sightings are the ground truth the forecast is measured against, and they sharpen its estimates over time.

Dealate Pro unlocks your own GPS location, searching any place, free map panning, and flight alerts; the free tier covers only the demo region, Austin / Central Texas. Dealate Pro costs $5.99/month, $12.99 per 3-month season, $24.99/year, or $49.99 for lifetime access, and starts with a 3-day free trial. The species odds, best-window view, 7-day outlook, and sighting log all work in the free demo region before you subscribe.

You report a sighting in Dealate using the in-app sighting log: record the species, place, and time of a nuptial flight you witnessed, and it joins your personal history. Your observations are citizen science for myrmecology — real flights are the ground truth Dealate's weather model is measured against, so every logged sighting helps sharpen the forecast for everyone. Logging works in the free tier; you do not need Dealate Pro.

Yes — Dealate works anywhere, but its free tier is pinned to the demo region, Austin / Central Texas. To get forecasts for your own GPS location, search any place in the world, pan the map freely, and receive flight alerts, you need Dealate Pro ($5.99/month up to $49.99 lifetime, with a 3-day free trial). The full forecast experience — species odds, best window, and 7-day outlook — works in the demo region before you subscribe.
