INTRODUCTION
At the end of the twentieth century, the interest and fondness for insects brought together some people from Gipuzkoa (one of the provinces of the Basque Country), who finally decided to give birth, in 1999, to the Entomological Society of Gipuzkoa. Currently only a part of the members are from Gipuzkoa, but the name of the Society remains, linked to its origins and to the centre of most of our activities.
This is a nonprofit association, which objectives are just the initial interests of that group of persons:
1- The study of the entomofauna surrounding us.
2- The spreading of the entomological knowledge..


Those two objectives and interests are mainly achieved through the publication of both journals of semiannual periodicity:
1- Heteropterus Rev. Entomol., since 2001, a scientific journal.
2- Heteropterus, since 2000, a spreading magazine.
Among the remaining activities developed by the Society, the inventory project Entomofauna from the Aiako Harria Natural Park has an outstanding relevance.
