The Colias edusa, or Clouded Yellow Butterfly, appears from time 

 to time in great numbers in many parts of the country, sometimes 

 scattered over a large district, sometimes almost as a flock over a 

 Clover field. The caterpillars do not appear to be injurious to any 

 notable extent ; still, as they do feed on various kinds of cultivated 

 trefoil (that is to say, both on the red Clover and the white Dutch 

 Clover, as well as on Lucerne, and other kinds of Legnminoscc, wild or 

 cultivated), the widespread appearance of the species again in the past 

 season is worth record. 



The bright yellow tints, and considerable size of the butterflies 

 fluttering in large numbers on a sunny day over some Clover field 

 which a flock may have selected for their presence, are an exceedingly 

 pretty sight. My own first observation of such an appearance was at 

 a date not long before 1800 (but of which I have not now a note of the 

 year), when the butterflies were observed in such great numbers on a 

 hot afternoon on a field of purple Clover in the west of Gloucestershire, 

 just above the Wye, near Chepstow, that I was called to look at them.
