Insects -- Collection and preservation
_Collecting Dung-beetles._--The collecting of the numerous species
(_Hydrophilidae_, _Staphylinidae_, _Histeridae_, _Scarabaeidae_, etc.) which
live in the droppings of various animals is by no means an agreeable
task. The collector should provide himself with a pointed stick and
collecting tweezers, and must manage to pick up the specimens as best he
can. The larger specimens are best collected in alcohol, while the more
delicate species can be collected in a cleaner condition by removing the
droppings and sifting the ground beneath the same. Some species hide
deep in the ground beneath the droppings and have to be dug out. Summer
freshets, when pasture lands are inundated, offer an excellent
opportunity for collecting the dung-inhabiting species in a clean
condition.
_Night Collecting._--The beating of trees and shrubs after dark is a
good method of obtaining Lachnosternas and other species, and here the
collector will do well to secure the assistance of a companion, who
takes charge of the lantern and the collecting bottles, while the
collector himself works the umbrella.
FALL COLLECTING.--From the first of August the number of species
gradually diminishes, but late in the summer or early in fall quite a
number of other species make their appearance, _e. g._, some
Chrysomelidae, Cerambycidae, and many Meloidae. Many of these frequent the
blossoms of Golden-rods, umbelliferous and other late-flowering plants.
The fall is also the best season for collecting Coleoptera living in
fungi. Although puff-balls, toadstools, and the numerous fungi and
moulds growing on old trees, etc., furnish many species of Coleoptera
also earlier in the season, yet most fungi, and more especially the
toadstools, flourish best in the fall, and consequently there is then
the greatest abundance of certain species of Coleoptera. Decaying
toadstools are especially rich, and should be sifted, and the collector
should also not omit to examine the soil beneath them.
During the "Indian summer" there is usually a repetition of the "spring
flight" of Coleoptera, though on a smaller scale, and collecting on the
tops of fence posts and on whitewashed walls again becomes good. The
first really sharp frost causes these late species to disappear, and
winter collecting commences again.
