THE YOUNG 



NATUUALIST. 



bloom a month, and consequently were 

 worn. Last year they frequented the rag- 

 wort as soon as they emerged from pupa. 

 Siispecta, which swarmed at the same flower 

 last year, never put in appearance at all this 

 year, not even a solitary specimen. Possibly 

 they had done flying before the ragwort 

 became attractive to insects. The ragwort 

 was in bloom about the third week in July, 

 but I found no insects at it until the end of 

 August. Similarly in 1878 I watched this 

 flower for three weeks without being 

 rewarded with seeing an insect. Last year 

 and the year before insects began to visit it 

 as soon as the flowers expanded. Is its 

 attractiveness so variable on the coast ? 

 How do you account for this ? Possibly, in 

 some way or other, the cause is connnected 

 with atmospheric conditions. — E. P. P.

Elder Growing Parasitic. — A few 

 months ago I saw an elder bush growing 

 parasitic out of the trunk of a sallow at 

 Leiston in Suffolk. I also saw two elders 

 growing in vegetable matter collected in 

 forks of trees — one at Leiston on a sallow, 

 the other on an acacia at Hacheston. The 

 bush that was growing parasitic had its 

 roots firmly fixed in the wood of the tree. 

 I have also seen brambles and gooseberry 

 bushes growing in matter collected in 

 crevices of trees. — Geo. A. Harker, 28, 

 Brooke Road, Brundell Sands. 



[Mr. Gregson has already called attention 

 to the fact that shrubs growing in such 

 situations as those mentioned above are not 

 parasitic, but one of those named appears 

 to be so. Will our correspondent take the 

 trouble to examine the elder growing on 

 sallow again and satisfy himself whether it 

 is really drawing its sap from the sap of the 

 sallow and then write us again. — Eds. Y.N. ] 

 Captures at Derby. — On September 

 2oth I captured a fine specimen of C. xer- 

 aynpelina which came into my house to the 

 light. I was rather surprised to see so 



! 



i scarce an insect, as I am living in the centre 

 I of the town and am not aware of any asti- 

 trees near. My friend, Mr. J. Hill, tells me 

 he has found insects rather plentiful this 

 last week or so : he has taken in two nights 

 at sugar 32 Rujuras 3 Litura, 3 Protea, 1 

 Miccacea, 2 Tragopogoiiis, and 7 Fenuginca. 

 Up to lately sugar has been a failure this 

 season here.— G. Pullen, Free Library and 

 Museum, Derby.
