INSECTS AND OTHER SMALL DEER. 139 



focussing some favourite flower and then waiting, 



but there is a tantalising perverseness about the 



creatures which prevents them from visiting any 



flower upon which 



the recording eye 



of a camera is 



fixed. 



As the vivacity 

 of most insects is 

 measurable by the 

 prevailing tempe- 

 rature, we tried 

 again one day in 

 the early part of 

 summer when the 

 thermometer was 

 low and inter- 

 mittent bursts of 

 sunshine cheated 

 a few butterflies 

 forth, and we suc- 

 ceeded in making 

 the photograph re- 

 produced on this page whilst the creature rested on 

 a turnip leaf. 



One great point which must be observed in 

 photographing insects is to make quite sure that 

 they are perfectly still, and that the object upon 

 which they are resting is not being swayed to and 

 fro by the wind.
