Thanks for saying you enjoy my snippets of information.
Actually this type of knowledge does help a great deal when trying to take pictures of insects. Look at Klaus's work relating to his extraordinary images of damselflies etc. The reason is simple. He gets up at some unearthly hour, finds his subject, sets up his equipment and fires away with all the time in the world. The reason being is that the critters are so damn cold that they are unable to move. And this is the secret.
I used to do the same. Up at 3.00am. Drive 100-200 miles. Arrive at destination. Find subjects and take their pictures and be home for 11.00am. By using this technique you can actually move dragonflies- butterflies etc. to the SPOT YOU WANT without any trouble whatsoever.
For butterflies the early morning is great, or a dull day. They will sit on the ground or their perch and bask to the weak sun and totally ignore you. They have no option but to sit their trying to warm up their flight muscles.
We say 'Mad dogs and Englishmen go out in the mid-day sun.' At least Noel Coward did. Well all you will get by going out at this time of day to photogrsaph insects is a hernia due to all the rushing about. So much easier to go out early, find your torpid subject, chat to it and tell it you are going to take its photo, set up, take its picture, thank it for letting you do this, go home and have breakfast. or an early lunch!!
Best wishes.
