Let's join a firefly tour Kuala Lumpur where you can find the fireflies are also known 'Lightning Bugs' and they shine brightly at the night to attract a suitable partner. They are only seen at night in and along the 'Berembang' trees along the Selangor River. We could not spot any in the palm trees or any other trees for that matter. Often their flashing becomes synchronized, the overall effect is just like the twinkling lights of a Christmas tree. A trip along the river banks at the Selangor River at night is truly magnificent, and definitely a great attraction that should not be missed.
