现在是发光时间(It's glow time)

在地下，洞穴探险家可能会发现这些地下空间被一种不太可能的光源照亮。在12月至3月的温暖季节，真菌小昆虫幼虫——更亲切地称为萤火虫——在澳大利亚洞穴的墙壁和天花板上布满斑点。对人类来说，它们无害得令人着迷，并为蓝山国家公园等地的洞穴增添了一点超凡脱俗的魅力，如我们的照片所示。但如果你是一只苍蝇或蚊子，小心！萤火虫悬挂着细小的、粘乎乎的丝线，诱捕着飞向星空的有翼昆虫，但事实上是洞穴的天花板，上面覆盖着萤火虫，耐心地等待着一只受骗的苍蝇。

Down under the land in the Land Down Under, cave explorers may find these subterranean spaces illuminated by an unlikely light source. Fungus gnat larvae – more affectionately known as glowworms – speckle the walls and ceilings of caverns here in Australia during the warm season from December to March. To humans, they're hypnotisingly harmless and add a little otherworldly charm to the caves in such places as Blue Mountains National Park, as seen in our photo. But if you're a fly or mosquito, beware! Glowworms dangle tiny, sticky silk strands that ensnare winged insects flying toward what looks like a starry night sky, but is in fact the cave ceiling, covered in glowworms, patiently waiting to reel in a deceived fly.
