Habits. — Beales observes (Ent. Pec, iv., p. 165) that the 

 imagines, whether forced or not, almost invariably emerge between 

 noon and 2 p.m. j Clark finds them newly-emerged on the trunks 

 of lime - trees in the afternoon, but James discovered a 2 just 

 disclosed, the wings undeveloped, on a lime trunk, at 10.30 a.m., 

 on May 12th, 1895, at Crouch End ; Russell states that 

 the imagines emerge during the daytime. During the day they 

 are to be found on elm trunks (Raynor) ; on lime-trees and palings 

 at Wimbledon, &c, on elm -trees at Oxford (Briggs) ; on lime- 

 trees in gardens and meadows at Sudbury (Ransom) ; on palings 

 and once on a bay-tree at Chiswick (Sich) ; on dark-coloured 

 barricades and fences at Namur (Lambillion). The well-known 

 position taken up by this moth when resting on a fence or tree- 

 trunk is highly protective, and it is said* often to rest on the 

 young shoots that spring directly from the trunk of a lime-tree, 

 and to simulate a group of small leaves ; I have seen one hanging 

 from the top of a split oak fence, and it so exactly resembled a 

 withered leaf that none but a practised eye could detect the differ- 

 ence (Bacot). Meyrick compares the imago at rest to a pair of 

 half-expanded lime leaves. In the evening Dillon has observed the 

 imagines at Clonbrock flying about lime and privet at dusk, and Kaye 

 (Ent. Pec, xii., p. 313) observed one at dusk, on July 15th, 1900, 

 hovering at honeysuckle, at Worcester Park. Hewett notes an 

 example taken at night on a sugared tree at Winchester (Ent. Pec, 

 ii., p. 133). The imagines are occasionally attracted by light. 

 We have taken it clinging to lamps at Strood and Peckham ; 

 captured at light on Wicken Fen (Studd) ; very common at 

 electric light at Berne, May 2nd — 10th, 1893 (Knecht); fre- 

 quently at light at Worcester (Rea) ; at light at Cheltenham 

 (Winterbotham) ; at Aigle, 7 examples, from 9.15 p.m. — 10.20 p.m., 

 on July 3rd and 4th, 1898 (Lowe); at the electric light at 

 Chester (Arkle). The males are readily attracted by a newly- 

 emerged $ ; Burrows and others record the capture of several $ s in 

 this manner, and Carter writes (Ent., xxxiii., p. 202) that a $ , hanging 

 on the lower branch of a lime-tree on May 17th, 1900, and following 

 days, attracted Js as follows: May 17th, 3 Js; 18th, 7 $ s ; 

 19th, 4 #sj 20th, 3 $ s ; 21st, none; 22nd, 2 $ s ; 23rd, 2 $ s. 

 He concludes, from his observations on this and other occasions, 

 that the $ s never arrive before 9 p.m., nor has one been observed 

 after 9.30 p.m. Jenner observed several males attracted at 8.30 

 p.m. by a newly-emerged 9 in a window at Carshalton, on June 

 15th, 1857. Bacot obtained 4 $ s between 8.50 p.m. and 9.25. p.m. at 

 Clapton, on May 7th, 1896, with a fresh ? . Prideaux obtained 

 3 $ s, attracted to a bred ? , between 9 p.m. and 9.30 p.m. at 

 Bristol. Lee took a dozen $ s one evening in June, 1888, at 



* The small leaves breaking out from the buds here and there on lime-trunks 

 nearly always appear in pairs, and point obliquely downwards, so that they form a 

 curious resemblance to the wings of the imago oi M. tiliae ; they are placed at precisely 

 the same angle, and when only half expanded have the same straight costal edge and 

 scalloped margin (Barrett).
