FIELD NOTES AND QUESTIONS. 



(Notes on rare or otherwise interesting captures, habits of insects, etc., will be 



gratefully received by the editor). 



Heliomata infulata Grote. This pretty little Geometer is 

 usually very rare here, perhaps only half-a-dozen specimens having 

 been observed in twenty years, but one day at the end of May 

 1913, while collecting in a locust thicket I noticed several specimens 

 flying and managed to secure two. A heavy shower came up, 

 compelling me to seek shelter, but after the rain I returned to the 

 spot and captured 20 specimens inside two hours. A few days 

 later I again visited the spot and was likewise disturbed by rain 

 but this proved advantageous as the moth which generally is very 

 shy and swift on the wing, appeared quite sluggish and easy of 

 capture. Eighty specimens were taken in all in a space of about 

 7 acres. In the surrounding district of 100 acres of apparently 

 the same conditions only a stray specimen or two could be 

 discovered.

How Lepidoptera Winter. We are not infrequently asked in 

 what stage butterflies and moths pass the winter months? It is 

 not an altogether satisfactory answer to say that every one of the 

 four stages is represented, as the enquirer is sure there must be 

 some rule and the others be exceptions. In Newman's "Text 

 Book of British Butterflies and Moths" 1913, there are 117 pages 

 devoted to a list of species, giving collecting notes in tabular form 

 and it may be of interest to know how the British species, in- 

 cluding the micros figure out, as doubtless in the cooler parts of 

 North America the proportion will be about the same. Counted 

 roughly and omitting species of doubtful occurrence, out of 68 

 Butterflies, 9 winter as eggs; 38 winter as larvae; 12 winter as 

 pupa 1 ; 9 winter as imagoes; of 781 moths, 10S winter as eggs: 300 

 winter as larvae; 330 winter as pupa?; 37 winter as imagoes; so that 

 about 80% winter either as larvae or pupae, almost exactly half of 

 each ; 15% as eggs and 5% as imagoes.
