Well maybe that would be a bit optimistic however, unless you were really unlucky, with a bit of effort it is certainly something you could achieve in two or three years. You would need to do a lot of research to find out where the best breeding sites are located. In my opinion the quickest route would be to join both the Butterfly and Dragonfly National Societies where members are privy to information and the main sites especially concerning some of the rarer species.
The Scarce Swallowtail
How could you disregard this stunning migrant?
At the same time join your County Group and go out on the weekend field trips which they will be running throughout the year. The latter will give you all your local sites plus you will learn a great deal about your subjects in general.
One of the really nice aspects about photographing these beautiful of insects is that the photography takes place during the most pleasant months of the year and normally in nice weather. Secondly you don’t need a great deal of equipment so, if weight or finance is a problem, this really could be the ideal starting place for you.
What you need next is to learn how to photograph them. They are very easy to photograph badly, not so easy to photograph well and even the most common butterflies like this Meadow Brown above can look really stunning. How do you do that? Well you could start off photographing them badly and hope to get better at some time in the distant future or you could attend my workshops and immediately start off photographing them correctly. Want to know how to get a butterfly to settle on a specific flower or a dragonfly to land on a photogenic perch that you set up? Sounds optimistic - but that is what the pros do.
