October special: monarch butterflies
10 monarchs seen Sep 22-Oct 5 vs 64 in 2025
That's fewer than last year, so a monarch would be a lucky find.
Monarch butterflies reported within 25 km in the 14 days before today (Sep 22-Oct 5): 10 (iNaturalist, checked Oct 6, 11:41 PM CDT). Same two weeks last year (Sep 22-Oct 5, 2025): 64.
Milkweed seen near this park: yes (317 iNaturalist sightings within 1.5 km, all years).
Tip: look on milkweed and on fall flowers on a sunny afternoon. Look, don't touch: let it fly.
