visible, but as it grows larger the other two pairs of ventral 

 legs become visible, though the first pair is not used.

End of May and June, and in a second generation in 

 September, upon Convolvulus arvensis, eating the leaves, 

 flowers, and seeds, feeding at night and reposing during the 

 day upon the stems close to the ground, lying along and 

 closely clasping the stems. 



Pupa red-brown, in the earth. Not more particularly 

 described. 



The moth flies in the sunshine in fields of clover, lucerne, 

 sainfoin, and Trifolium incarnatum, in meadows, fields, and 

 on chalk hillsides, buzzing at the flowers of these plants, and 

 at those of wild thyme and other Labiates, but in dull weather 

 it seems to be quiescent during the day. At late dusk it also 

 frequents flowers, but is difficult to see in flight, though it is 

 gentle and not swift in its movements, and may be taken 

 with the help of a lantern. Very rarely it has been observed at 

 light. Extremely local and very uncertain in its appearances ; 

 formerly plentiful in Surrey, Sussex, and Kent, and has even 

 been taken at Lewisham in the London suburbs, now scarcer 

 and much more local in these counties ; more frequent in the 

 Isle of Wight, Dorset, and the south coast of Devon ; much 

 more rare in Somerset and Gloucestershire, but found locally 

 in Wilts, Berks, Oxfordshire, Cambridgeshire, and Essex, 

 and in more considerable numbers in the Breck-sand district 

 of Suffolk and Norfolk. This, however, seems to be the 

 extent of its range in these islands. Abroad it is common 

 throughout Central and Southern Europe, Livonia, Bithynia, 

 and other parts of Asia Minor ; Morocco and other portions 

 of Northern Africa, and in the mountainous regions of 

 Central Asia.
