Nice and orderly. Some sort of 'crab fly' that seems to always maintin body direction upwards and are capable of moving sidewards. As can be seen on the photo they occur in groups on palm leaves. The photo was taken on the 3rd of February, 2009.

If you have any idea what these flies are then please get in touch. They are almost the same size as the fruit fly, Drosophila melanogaster.
