Very quickly, the whole abdomen was aligned again eventually.Some years ago, I was rather lucky to witness how a Prodasineura notostigma damselfly, another common species curled up its abdomen. The last section of the abdomen started to bend downwards.
Next the second or the third last section began to follow suit. This motion of bending the abdomen was rather gradual and not so "violent" . One more section of the abdomen was seen curling downwards.
Now, it almost completed the bending motion. What a nice shape it formed. Until today, I have not seen this kind of motion again. What is the purpose of all these ? I am still looking for an answer.
