 The protective movements of the conspicuous larva 



OF THE CaTOCALINE MOTH, COCYTODES COERULEA, GuER. — 



Prof. PouLTON exhibited the coloured figure referred to in the 

 following record by Mr. H. W. Simmonds of Waidoi, between 

 Suva and Navua, Viti Levu, Fiji; also the moth bred from 

 one of the laxvae by the same naturalist. 



Oct. 18, 1919. — " I enclose a drawing of the larva of a moth, 

 one of three I found on a bush. When the bush was approached 

 it lashed its anterior segments violently from side to side in 

 a most alarming manner, shaking the whole branch violently. 

 I had a couple of weeks earlier noticed these three larvae, 

 then small, feeding in company with about 40 or 50 others 

 of a different species. Some three hours later the whole of 

 these latter had disappeared and only the three remained. 

 A company of wax-eyes in the adjoining forest suggested the 

 cause. I am pretty confident that if the three larvae had 

 been as big as they were on my next visit no bird would 

 have dared to approach it, and both species would have 

 escaped." 



Moths flying, but not at rest, captured by Bats. — 

 Prof. PouLTON drew attention to an observation by Mr. 

 W. Feather at Kibwezi, B.E. Africa :— 



Feb. 1, 1920. — " I was much interested in watching the 

 bats flying in the room and taking moths, mainly Cyligramma 

 lafona, Cram., and limacina, Guer. As long as the moths 

 were on the wing the bats caught them, but immediately 

 they came to rest on the walls or ceiling they were quite safe, 

 the bats, although flying past them quite close, never attempt- 

 ing to take them. It seems as if the bats can only recognise 

 moths when on the wing." 



Musca autumnalis, De G. (corvina, F.), hybernating 

 IN a loft at St. Helens, Isle of Wight, as in 1914-15 and 

 1917-18. — Prof. Poulton said that he had visited the loft 

 on Dec. 16, 1919, and found one long narrow patch of many 

 hundred flies and another small one of several dozen. A 

 few were swept by hand from the former patch into a small 

 box, and, when examined, were found to consist of 11 (^ and
