Nature Walk & Nocturnal Black Light Exploration: Live Oak Park – CNC 2026

From daylight to dark — explore Live Oak City Park by day, then discover what comes out at night under UV black lights. No experience needed.

With its lake, wooded trails, and open meadows, Live Oak City Park is packed with habitat — and that means it's packed with life. Most people come here to walk, fish, or play. We're coming to find out what else calls this place home.

On Sunday, April 26, join Robert Doyal, Leia Lozano, and Tracey Burke, Texas Master Naturalists and iNaturalist Ambassadors, for an evening that unfolds in two parts:

Nature Walk & ID Session · 5:00–7:00 PM
We'll head out from the Treehouse Playground to explore the park's trails and habitats, using the free iNaturalist app to spot, photograph, and document what we find along the way. We'll stop along the route to talk through what we're seeing, how to identify it, and what makes a strong observation. No experience needed. If you can point a phone camera at a bug, you're qualified.

Nocturnal Black Light Exploration · 7:30–10:00 PM
When the sun goes down and the park goes dark, a completely different world wakes up. We'll set up UV black lights, and as the night deepens, moths, beetles, and insects you'd never see during the day will start showing up. You'll get to photograph, identify, and document them up close. This is hands-on, and it's unlike anything you've done on a nature walk before. A flashlight, headlamp, or phone selfie light will help you get a closer look and better photos.

Come for both, or drop in for the part that interests you most.

This walk is part of the City Nature Challenge, a worldwide event where people in hundreds of cities spend four days discovering and documenting the wildlife around them. Everything you photograph becomes part of a global biodiversity dataset — and helps scientists better understand what lives right here across our 12-county San Antonio Metro Area. That moth drawn to the light? That's data. The beetle you'd never have spotted without a UV glow? That's a contribution. You're not just going for a walk — you're mapping what lives here.
