82 LIST OF FLIES. 



Black ant flies. Numbers struggling on spider webs wove 

 in the angles of posts and rails by the water sides, where 

 numbers of the larger, as well as the smallest flies of the 

 day, are held fast in their fine fibred toils. Ambry at the 

 feet and end of body. 



Red ant fly. Took one off a spider's web at Eobin Hood, 

 which sparkled in the sun with fire and gold, and of a dull 

 amber transparency. Full length, near three-eighths ; wings 

 an amber tinge. 



Red dun. Full length, three-quarters ; length, half an 

 inch ; feelers, half an inch. Altogether of a dullish red or 

 ambry hue ; upper parts a shade darker. Body nearly 

 cylindrical, with a few short hairs round the last joint ; top 

 wings slightly broken with veins and faint freckles ; under 

 wings thin and uniform, of a light shade of amber when 

 looked through to the light, a red ambry tinge altogether. 

 This fly was hatched in a water pot. The creeper was put 

 in in May or June, and soon after fastened itself to the 

 side, near the bottom, and was hatched on the 18th inst. 

 The pot stood in the garden, and the fly was found float- 

 ing on the water, alive and perfect, with its empty creeper 

 skin beside it, and its empty artificial case fast to its original 

 place. The pot was covered with a piece of gauze, fastened 

 to a wire hoop, to prevent escape. 



Late black gnat. Out in the daytime. 



NOTE FOR AUGUST. The change of temperature of the 

 air begins to tell on insects this month, and swarms of the 

 tender tribes are swept off, but the waters continue full of 

 creepers, the constant breeders are unimpaired, and the sec- 

 ond swarms of some are turning out more numerous than 

 the first. The extracts for the month are taken from notes 

 made on fishing days and other times of research and obser- 

 vation, during the seasons of many years, which, after num- 

 berless close examinations and corrections, formed the foun- 

 dation of the list of flies. The aquatic flies mentioned in them
