INSECT WEATHER PROPHETS

If spiders are busy spinning their webs, fair weather may be expected, but if they are resting, the fact is an indication of impending storms or wet weather, some naturalists say. The reason is that the spider, knowing that its prey will not be abroad during rains or other unfavorable conditions, does not trouble to make its nest at such times. but prepares it for catches during fair weather. Bees are able to tell approaching storms and in threatening intervals will not venture far from their hives. The noise of the screech owl at night is also claimed to be an indication of fair weather.
