The processionary moth (eikenprocessievlinder) originates from southern Europe and lacks natural predators in Belgium. As such large caterpillar populations occur in spring. This is an issue because of their poisonous defensive hairs. These hairs break off easily and become airborne, causing skin irritation and in some cases even asthma.
The Province of Antwerp wishes to better anticipate possible hazards and has therefore creates a website where citizens can report sightings of the oak processionary moth.
This reporting is done via a map and the interface has been made with ArcGIS and Geocortex. The GIS department province has been able to create this site without the need for external consultancy.
