Blog Postings

The postings will be introductions to each of my life lists. The lists themselves will appear in the side margin. I shall do some postings about particular localities and there will also be postings to provide updates every time I add a new species.
Please note that I am not qualified in any aspect of natural history - there will therefore be occasional (or, apparently, in the case of the hoverflies, a lot of) errors.

Bugs


Although the term 'bugs' is used by the general public as a synonym for insects or small invertebrates generally it has a specific meaning to the entomologist - insects in the order Hemiptera. In order to clarify the meaning, members of the order are sometimes referred to as True Bugs.


Bugs are small to moderately large insects with a large, horizontally held head which is generally visible from above. In most species the forewings are partly chitinous and the hindwings membranous but may be absent. They possess a sucking or stabbing proboscis. Bugs have widely differing shapes and habits and some confusion with beetles, cockroaches and psocids is possible.


My favourite bugs are the shield bugs – 11 species seen and photographed so far - which have a fairly distinctive shape and are comparatively easy to recognise as adults. As nymphs, especially in their early instars, they are a lot less easy to recognise but it all adds to the fun. My least favourites are the aphids and as yet I haven’t tried to list the individual species seen.
