pins are useful for many species which are liable to form verdigris on the
pins, and are universally employed by many entomologists, but are probably
not so strong as the silvered ones.
Many species of moths are only to be found at night. When working at this
time the collector must suspend a bulls-eye lantern round his neck or
waist, and can then have both arms free for capturing insects on the wing
or at blossoms. Honey mixed with a little rum, and applied with a small
brush to the trunks of trees a few minutes after sunset, will, on some
evenings, attract large numbers of valuable species, but not infrequently
it is quite unproductive. This mode of collecting has been termed
"sugaring" by entomologists, and may be employed during the whole summer.
The best blossoms for attracting insects in New Zealand are those of the
white rata,[2] which blooms in the forest from February till April, and
from which the {14}collector may generally rely on getting a rich harvest.
The insects can usually be slipped directly from the flowers into the
killing bottle.
This is much better than netting them, although occasionally one will
escape during the process. When dead the specimens should be placed in a
small tin box which has been filled with cotton-wool, packed very lightly.
In this way a large number of moths may be carried a long distance with
perfect safety, and the extremely inconvenient process of pinning them in
the field obviated. If Jahncke's patent boxes are employed it is quite
unnecessary to kill the moths in the field. They can be boxed directly from
the blossoms and taken home alive without suffering any injury.
Lepidoptera, and in fact all insects, are attracted by light, and in some
situations the collector will find that he may frequently obtain good
species by merely opening his sitting-room window and waiting for the
insects to arrive. Much of course depends on the situation of the
collector's residence and the nature of the night, which should be dark and
warm. I have occasionally tried taking a lamp into the forest to attract
insects, but have not met with much success. In swampy and flat situations,
no doubt, attracting by light would be very effective, especially if a
powerful lamp was employed, in an exposed situation, with a sheet behind
it, supported between two poles. This method has been followed with great
success by many English entomologists in the fens, but has not yet been
tried in the New Zealand swamps, where it would probably be the means of
bringing many new and interesting species to "light."
