I am placing a large proportion of my wide-ranging and ever-growing natural history photographic library on Flickr as a hierarchical reference resource to assist in the critical identification of British wildlife. The collections for insect groups such as bees, wasps, hoverflies, plus soldierflies and allies are designed to be used in conjunction with the main identification literature for these groups (e.g. 'Field Guide to the bees of Great Britain and Ireland', 'British Hoverflies' and 'British Soldierflies').
In terms of copying/downloading these photos, I have no problems with non-commercial usage by private individuals. However, if your requirement is commercial or you are a funded organisation, please contact me to discuss what you wish to use them for and to gain formal permission for usage, otherwise you will be infringing copyright.
