Migration and Dispersal of Insects: Lepidoptera. 
By J. W. TUTT, F.E.S. 
Dr. Hamilton, writing from Brigantine Beach, New Jersey, in 1885, 
reports: ‘The multitudes of this butterfly that assembled here the 
first week in September is almost past belief. Millions is but feebly 
expressive. Miles of them is no exaggeration. On the island is a 
strip of ground from 150 yards to 400 yards wide, and about two and 
a half miles in length, overgrown with Myrica cerifera (bayberry). 
After three o'clock the butterflies, coming from all directions, began to 
settle on the bushes, and, by evening, every available twig was 
occupied. To see such multitudes at rest, all suspended from the 
lower sides of the limbs, side by side, as is their well known custom, 
was something well worth seeing. One evening, I travelled more than 
half the distance of their encampment, and learned that it extended 
the whole length and breadth of the bushes. In the morning they 
eradually separated, and did not appear unusually numerous during 
the day, but in the afternoon they came again as described. I found 
them on the 2nd, the day of my arrival, as related above, and this was 
repeated daily till the 6th, the forenoon of which was rather calm and 
sultry. A storm of wind and rain came on about 2 p.m., continuing 
until midnight. The next afternoon few came to camp, the great 
army had disappeared. But how? when? where? During the next 
few days they appeared again in considerable numbers, about as 
numerous as they had been observed in former Septembers, but 
insignificant when compared with those that preceded. The males 
and females were about equal in numbers. Not a sinele stalk of their 
food-plant (Asclepias) grows on the island.” 
On September 23rd, 1886, Dr. Ellzey reports (Insect Life, i., p.
