Nighttime Bugs: Augustine Staging Area

Join us for this evening program as we explore biodiversity at the local level with that most diverse group of organisms, the insects! Taking advantage of the fact that UV light is highly visible to most insects, we will attract them by using black-lights (low energy/low frequency UV lights). We can then examine them up close, record the different types (and their numbers). Don’t forget your camera as you’ll see creatures that are normally buzzing around, but not highly visible. You will be able to help us document what we find.
