Before you have been collecting long, you will have learned by observation quite a lot about insects and their ways. You will know that some localities are very poor collecting ground, that other places yield an abundant variety; that the best time for butterflies is in a sunny forenoon; while moths are abroad in the early twilight and later. You will see that dragon flies are fond of flying about over streams or ponds and you may wonder why as you try in vain to net a fine one without getting your feet wet. Other insects are frankly aquatic and you can get them only by dipping your net in. It is well to have a second net if you expect to do much water collecting as the cloth is hard to smooth out after a wetting. As a majority of insects are vegetarian you will naturally seek among plants for specimens. If the winged forms are not eating the foliage you may discover that they are laying eggs on the leaves of the food plant on which their young must develop. If you live in town you will find it worth while to carry your bottle with you when you go out in the evening. Nocturnal insects of all kinds are attracted to electric lights, many of them to their death, as you will see. A candle in your open window will attract some valuable additions to your collection and also some you will sleep better without. Some collectors care nothing for a specimen unless it is rare. A better way is to regard them all as rare until you secure a specimen for your box, and of equal value towards building up a complete collection. A LIFE HISTORY COLLECTION You can not collect insects very long before you begin to see a lot of things you never noticed before. You see leaves cut or eaten in strange forms, or you find a cluster of tiny eggs on a leaf, or several leaves sewed or stuck together with strands of silk. Perhaps you find strange abnormal growths on certain plants, swellings on their stems, leaves transformed into balls, or pod-like or cone-like affairs which do not look natural. These things are sure to arouse your curiosity. Sometimes the answer to your question is right there. Cut open a swollen golden-rod stalk and you will find the culprit which caused the plant to grow that way. But how did the footless, helpless grub get there and when? You break down the mud-dauber wasp's nest from among the rafters of some building. What is that yellowish object that rolls from among the ruined adobe walls? Look! It is a spider. What business has a spider in the wasp's nest, if it is her nest? Spiders have none too good a reputation, but this spider does not act very spry. Seems to be alive, yet not alive.
