Have just see a long line of 'Processional Caterpillars' . I first drenched them in lighter fuel and then set light to the buggers. I also found this site to be very informative http://www.practicalspain.com/spanish-arthropods.htm Keep an eye out for them apparently  'mid to late February' they are at their most dangerous.
