This termite alete (the first I've seen on Crete) could be an indication of a northward spread of these troublesome insects which have also been reported in Spain, France and Italy.

Cubitermes termitaria in the savannah
Only two species of termites have been recorded in continental Portugal (a couple more have been accidentally introcuded to the Azores): Kalotermes flavicollis and Reticulitermes grassei (formerly Reticulitermes lucifugus grassei). ID based on the morphology of workers is difficult, but the soldiers seem less robust and with a smaller thorax than those of Kalotermes flavicollis (check http://sostermitas.angra.uac.pt/termitas/, they have an photos of the various species that occur in the Azores side by side, including the oes that do not occur in mainland Portugal).
See throw, little bugs, resemble ants
Termites are a group of eusocial insects that, until recently, were classified at the taxonomic rank of order Isoptera (see taxonomy below), but are now accepted as the infraorder Isoptera, of the cockroach order Blattodea. While termites are commonly known, especially in Australia, as "white ants", they are for practical purposes unrelated to the ants (although they are prey to some ants, including the acrobat ant).
