OtherPix: 4: Side by Side
This photograph (made in Greece in July 2010) illustrates a different type of interaction between two species. The situation was as follows: we were standing below a tall tree with high overhanging branches when we noticed a male Odalisque (Epallage fatime) looking down on us. So we extended our tripod as far as it would go, raising the central column fully and folding its legs close together to gain an extra bit of height, and made some lovely photographs of the scene. Now, as you know, the Odalisque has the typical habit of perching with its wings spread out wide and when it does so, these outspread wings present an apparently irresistible perch for other damselfly species. In this case a male Beautiful Demoiselle (Calopteryx virgo) simply couldn't resist the temptation and decided to land on one of those wings. But our Odalisque was not amused and tried at first to rid himself of his unwanted guest by shaking his body about. But when the Demoiselle kept coming back for more, the Odalisque decided he'd had enough and simply (and suddenly) dropped the relevant wing like a trap door, sending his guest tumbling down. This time the Demoiselle did receive the message and didn't come back again.
