Spiders

There are certain days of the year when the immense wealth of spider industry going on all around us is revealed in a way calculated to strike even the least observant. We all know—and derive no peculiarly pleasant thrill from the knowledge—that we can, if so minded, find abun...

Chapters

9. CHAPTER IX

Of the groups of wandering spiders, which spin no snare but trust to speed and agility for their food, the Lycosidae or wolf-spiders supply the best subjects for study. To begin...

11. CHAPTER XI

It is quite impossible in a work like the present to deal with the classification of spiders. About forty families have been established, some of them of vast extent, the Attida...

15. CHAPTER XV

In the foregoing pages we have been able to deal with very few out of the vast number of known spiders; yet the examples we have chosen for study are fairly typical of some of t...

13. CHAPTER XIII

Seeing that the possession of spinnerets is a characteristic of all spiders, and that a great deal of the interest attaching to their life-history arises from their spinning ope...

4. CHAPTER IV

Before leaving the garden-spider let us undertake some little investigation of its mental powers—if it possesses any. The commonest mistake with regard to all animals is to inte...

10. CHAPTER X

We are not in the land of the jumping spiders or Attidae, and our few and sober-coloured examples of the group give but a feeble idea of the Attid fauna of tropical countries wh...

5. CHAPTER V

There are some interesting variants of the circular snare spun by some exotic Epeirids. One North American species spins it in a horizontal position and then raises the centre,...

6. CHAPTER VI

Before going farther afield, let us investigate one of the spinners of the sheet-webs that are so unpleasantly familiar in the house. We object to them on very obvious grounds,...

2. CHAPTER II

Not many years ago the group Insecta was held even by Zoologists to include numberless small creatures—centipedes, spiders, mites, etc.—which further study has shown to present...

14. CHAPTER XIV

When one comes to consider the multitudinous risks to which a spider is exposed during the whole course of its life it seems at first a little surprising that the whole tribe ha...

3. CHAPTER III

Select the most perfect circular snare at hand, and examine it attentively. In the autumn, when the large garden-spider, _Epeira diademata_ (fig. 2 _A_), is mature, it will prob...

7. CHAPTER VII

Here is the place to insert a short account of some near relations of _Agelena_ which we shall certainly not meet in our walk, but of which the mode of life is too interesting t...

8. CHAPTER VIII

All spiders can spin, but by no means all use that power to entrap their prey. Many have no settled abode or resting place except perhaps for a short time when they are rearing...

12. CHAPTER XII

Many of the Arthropoda—the large group which includes insects and crustaceans as well as Arachnida—are able to produce sounds, a fact familiar enough in such insects as crickets...

1. CHAPTER I

There are certain days of the year when the immense wealth of spider industry going on all around us is revealed in a way calculated to strike even the least observant. We all k...
