While visiting Thailand and peninsular Malaysia this month, I got to see many exciting firefly education and conservation initiatives. Here’s a glimpse of some conservation action happening right now in Thailand:
- Winding down to the sea, the Chao Phraya River curls around the unspoiled island of Bang Kachao, an area known as the green lung of Bangkok. Although mere minutes from downtown, Bang Kachao is home to a surprisingly robust population of the synchronous firefly Pteroptyx malaccae, whose males take up perches in particular display trees and all flash together in unison to attract females. My colleague Dr. Anchana Thancharoen has established a firefly education center that trains local volunteers to survey firefly populations along a raised bike path through the mangrove forest. Unlike in many other places, these particular fireflies seem unperturbed by the bright lights that illuminate the path – even some trees completely bathed in artificial light have fireflies. Perhaps this population has somehow managed to adapt to such high ambient light. Yet I wonder – without real darkness giving visual contrast to their flashes, can these males still manage to attract females?
- Situated within the Phrom Yothi Military Camp in Thailand’s Prachinburi Province, Firefly Land hosts the terrestrial firefly Asymmetricata circumdata. Many tourists come to see their impressive mating displays on weekends. The government is working to protect the fireflies while still allowing people to enjoy the show. They recently installed a fence that prevents visitors from tromping through the fireflies’ habitat, and constructed a raised walkway leading to a covered viewing platform. They even turn off the street lights during the nightly courtship period!
