Latest observations of Invertebrates

The term "Invertebrates" covers a very broad group, including insects, worms, molluscs, arachnids, and many others, that tends to get lumped together under the heading 'bugs' or 'mini-beasts'. The vast majority of all animal species are invertebrates, and estimates of the number of species in the UK range up to 30,000 or more.

Within this huge number of species there are animals that specialise in almost every conceivable habitat, and their life-cycles are correspondingly varied.

We will be providing additional information on the individual groups of invertebrates, but for now the list of links below just gives some examples for the major groups.

Photography for identification

The characters needed for identification vary between the different groups, so the general advice is to try and get shots from various angles, including close-ups and more distant habitat shots for context. Size matters! If there is nothing in your photo to give a sense of scale you should measure or estimate the size and keep a note of that.
