As there has been some curiosity to know in the supposed necessity many flowers have for cross-fertilization by insect agency how it is done in early spring, before winged insects are common, the writer of this made notes of the earliest seen. The first night flyer caught was on the 10th of May - He-liophila Harveyi. These were in great abundance up to near midnight, and perhaps longer. A few days after the same insect was caught abundantly at mid-day, sucking honey from flowers, in company with the bees. Mentioning the matter to Mr. Wm. Saunders, the distinguished editor of the Canadian Entomologist, produced the following note: "We have very much yet to learn regarding the voluntary activity of insects. It has long been observed that many night flying species which usually rest during the day will, if disturbed by man or other enemies, fly about with considerable activity, even in the middle of the day. The common mosquito is a day flying insect, but is also very active during most of the hours of the night. While sugaring recently with the view of capturing moths, I have found my bait almost every night being fed on by swarms of mosquitoes actively buzzing about in the darkness at least as late as midnight, and I presume longer.
Several species of ants, too, which are active during the day, are very abundant and lively at sugar during the same hours. One of the species of Plusia - simplex is, I know, a day flyer, another species closely resembling it, precationis, I believe usually flies at dusk. It would be well to record all observations of this kind. We have all been too ready in times past to accept as established facts many things which have never been satisfactorily proven."
