See my other video: Damselfly devours a mosquito (http://www.youtube.com/watch?v=3GgUlj...)
Damselfly larvae are carnivores which lurk among leaves or plants, waiting for prey to approach. The damselfly larva in this video clip is Pseudagrion australasiae, an uncommon species in Singapore. It is 23 mm long and the fish is 7 mm long. Once the damselfly larva senses something moving below it, it quickly turns its body around and makes its first, but unsuccessful, attempt to catch the fish with its elbowed labium. If you watch the clip carefully, you would be able to see the fish swimming away from the extended labium of the larva. Soon the fish comes back and this time the damselfly larva manages to secure its meal. The action is too fast for my camera (running at 25fps) to capture clearly. The damselfly larva then slowly consumes the whole body of the fish, except the head.
