The moth of the climbing cutworm, Hadena arctica which was such an unwelcome intruder in houses in the season of 1895, was again in evidence, but in moderate numbers. The superabundance of the Milkweed butterfly, Anosia archippus, (Fig 62) attracted general attention, even amongst those who are not in th9 habit of noticing butterflies. It appeared early, and kept increasing in numbers until about the end of August; whilst specimens of it were taken as late as the middle of October. One of our members who lives in the country, a short distance from the city, told me that he was out in a field one evening when he saw them in great numbers hanging to the heads of grain, and that he picked off several dozens of them with his fingers. Another of our members informed me about the end of August, that he had been in a wood to the North-East of the City with his dog, which started them up by the hundreds from bushes where they had settled down for the night; and he thought it something very strange, but I had no difficulty in showing him from books that it was a well-known habit of theirs. And yet this gathering in flocks at a particular place to pass the night together like birds, long before their time for migrating has come, is indeed a singu- lis- 63- lar disposition for butterflies to display. (Fig. 63.) During daytime they care nothing whatever for each other's company, but fly aim- lessly about as solitary individuals, as if they were in a meditative mood. When, with night's approach they begin to congregate at their rendezvous, then they cannot get close enough to each other ; but will crowd themselves in where there ia no room, to the great inconvenion
