The species pages all have a common structure. The first page provides a brief account of each species in referring to its distribution and abundance in Ireland, adult flight period, preferred habitats and identification. Key identification features and similar species are mentioned. This is accompanied by a photograph of an adult male of each species which changes to the female, larva or Irish distribution map when your mouse pointer is moved over these hyperlinks in the table at the top of the page.
By clicking on the photograph or hyperlink you can view these pictures and the maps at larger size within the Gallery. If the pictures seem too large please note that the site is designed to be viewed on a 17 inch monitor at XGA (1024x768 pixels) or higher resolution and true colour. Click on each small picture in turn to bring up the next image or backtrack by clicking on the large picture.
From the species account click on Biology to access a separate page with pictures of the larvae and more detailed accounts of the biology of each species with information provided under the following subheadings.

Flight period: flight period in Europe (source Askew, 1986) and in Ireland (from all records)
Adult habitat and habits: more detailed information on the habitat and habits of adult part of lifecycle
Oviposition site and behaviour: detailed information on behaviour and sites used for egg-laying.
Larval habitat and habits: information on larval behaviour and habitat preferences.
