Damselflies at Belumut – Mating

One of the interesting behaviors to watch in Damselflies is mating! What time do they usually mate? For how long? Any foreplay? What do they do after mating? etc.

I was fortunate to observe 7 pairs of mating damselflies at Gunung Belumut Recreation Forest during our recent recce trips. I have seen damselfly species mated for hours but those that I saw at Belumut were much shortly. Here are some interesting mating facts of 3 uncommon species that I was lucky to capture within the same day:

Libellago aurantiaca & Heliocypha biforata : mating time 11 am to 3 pm, female suddenly appears from no where and starts mating (in wheel position or love shape formation), mating lasts approximately 90 sec, after separation, female immediately lays eggs at nearby log while male stands guard. With such a short mating time, it is not easy to capture them in pixels not to mention refining your shots. I was lucky to be at the right place and right time.

(Heliocypha biforata)

Neurobasis chinensis : mating time 4 to 6 pm; male and female would attach together in tandem first usually about 1 to 2 mins, very skittish when they are in this tandem position. No point moving closer as they would not allow you to do so. It is best to let them settle down to form a mating wheel position; mating lasts more than 4 minutes; after separation, male & female go separate way, not sure whether female lay eggs immediately.
