Firefly viewing rules: keep quiet, do not expose to strong light, do not shoot with flash
Fireflies are susceptible to human interference. Fireflies emit light mainly for defense and courtship. The Agriculture, Fisheries and Conservation Department reminds people to observe the following rules for viewing fireflies:
1. Do not catch fireflies or their larvae.
2. Do not irradiate fireflies with flashlights or other strong light, or take pictures with flashlights (red filters should be added to the flashlights, or red cellophane should be used to avoid light pollution), so as not to affect the defense and courtship behavior of fireflies.
3. When watching fireflies, keep the surrounding environment quiet so as not to disturb other wild animals or nearby villagers.
4. Never enter streams or ponds to avoid accidents.
5. Take away rubbish and keep suburban environment clean.
