Larvæ may now be taken in abundance by beating the boughs of oaks and other trees, and also by examining low plants.

The hybernating butterflies are still on the wing, and the following are also out:

There is a great increase in the number of moths this month, and much good work may be done by means of light traps and by the examination of fences. Many moths are driven from their resting places early in the morning by the direct rays of the rising sun, and then seek out a spot where they are better sheltered, and where they are consequently less easily found. Hence the advantage of searching fences early in the morning.

The May list includes:

A number of the Micros are also out this month. About twenty species of the Pyralides, one or two of the Pterophori, a few Crambi, about fifty of the Tortrices, and no less than two hundred of the Tineæ. The collector will do well to search fences and

tree trunks for these moths, whenever he has the opportunity; and also to use the net freely in wooded country, waste places, and along hedgerows, before and at dusk.

JUNE

There is a marked increase in winged insect life during this month. The early butterflies are disappearing, or perhaps have quite left us; but new species are taking their place. The Sphinges now reach their maximum, as do also the Bombyces; and the other groups are almost if not quite up to their highest total. The Noctuæ and Geometræ each amount to over a hundred species. No less than a hundred and fifty British Tortrices are on the wing; the Tineæ make a near approach to three hundred, and the Pyralides of the month are not far short of numbering a hundred species. It will thus be seen that the net and pill boxes, as well as the setting boards, are in constant demand.
