Why Do Earthworms Come Out In the Rain

Earthworms belong to phylum Annelida, subclass oligochaete. The common names used for earthwords are dew worms, rainworms and angleworms. Also known as big worms, they are the largest members of the subclass oligochaete. Their length ranges from 8 to 10 inches; some species, however, can attain a length of 12 feet even.

On the contrary, some earthworms may reach a growth of just 1 inch. Till to-date, about 2500 species of earthworms have been identified. They have exotic colors such as reddish, dark gray or black in color.

You might have noticed that after drizzle, earthworms surface in gardens, on walkways, and intrude across neighborhood lawns, to feast local birds. Modern humans have no time to look such natural phenomena because of their outlook detached from nature.

Earthworms Why Do Earthworms Come Out In the Rain

There are numerous related issues to explain as to why worms appear after raining, but the shortest of all versions is that they exhibit this behaviour because they find environment over ground peculiarly favorable and offering.

A common cause attributed to this kind of behavior of worms is that they have to vacate their burrows after extensive drizzling has happened because otherwise they drown. If pondered at logically, the contention seems to be justified and self-explanatory; they really do!

Respiration in worms operates on the natural phenomenon of gaseous exchange, sifting in oxygen molecules through their skins directly from the air in contact. As long as there are sufficient quantities of oxygen dissolved in water, worms can easily survive for a number of days even if drowned in water all over, as modern scientists with innovative ideas have pointed out.

The pattern of worms breathing, however, explains why they are used to flock above the ground when rain has taken place. Worms are enveloped by mucus that conducts gas exchange, with the result, they remain moist. Mostly weather on earth is too hot to dry out for a worm and eventually cease to exist because it can’t breathe with mucus dried out in sun.

When drizzling is just done, the environment is damp enough to facilitate the breathing process and also making it convenient for them to crawl along the ground; this makes worms dare to surface. Worms prefer to mate above ground. This is another stimulus that earthworms surface out to do it with all the essential locomotion.

In other words we can be safe in so far as to say with little credibility that worms come out after a rain with the intention of finding prospective mates, considering the world on ground a sort of worm nightclub, with a variety of potent mates available out there.

Apart from usual post rain surfacing ventures, worms often intrude the on-ground world at night as well. In the evening, when the air is considerably cool, and the environment damp enough to support an earthworm appear on ground. People who pierce worms as bait for fishing mostly prefer the evening time for hunting “nightcrawlers,” to get advantage of this feature of worms for fishing trips.
