_Bees, Wasps and Ants._--Bees, wasps and the winged form of ants have four transparent wings, Fig. 140. Some flies resemble bees and wasps, but if examined it will be found that they have only two wings instead of four. [Illustration: _Fig. 142. The Cabbage butterfly._] [Illustration: _Fig. 143. The Bass-wood leaf-roller moth._] _Butterflies and Moths._--Butterflies and moths may be told apart by the following character: The antennæ or horns of the butterflies are always threadlike and knobbed at the tip, Figs. 141, 142, while the antennæ of moths are in various shapes, but never bear knobs at the tips, Figs. 143, 144, 145, 146.

[24] Teachers' Leaflet No. 5, June, 1897. It is unfortunate that there is, throughout the country, a prevailing dislike for the small creatures called "worms." This dislike is, in most instances, the result of wrong training, and is by no means a natural instinct. As evidence of this, witness the joy with which the small boy or even the small girl, handles "bait" when preparing to go fishing; although of all common "worms" surely the angle-worm is least attractive from any point of view. A still more striking example is the hardihood with which young fishermen catch the dobson to use as a lure for bass--for the dobson is not only very ugly in appearance but is also vicious, often pinching severely the careless fingers of its captors. Thus the dislike for insects being the result of the point of view, it should be the first duty of the teacher to remove this repulsion. In the lesson which follows there is no occasion for teacher or pupils to touch the insects unless they choose to do so; but an attempt is made to arouse an interest in the habits and ways of insect life. If we can succeed in arousing the child's interest in the actions of a caterpillar, he will soon forget his dislike for the "little brothers" which live upon foliage and which experience miraculous changes of form during their short lives.
