Common Name: Sowbugs, Pillbugs
Scientific Name: Varies
Order: Isopoda
Description: Adults grow to about 3/8 inch long, have a number of rounded body segments and seven pairs of legs. Sowbugs possess a pair of tail-like structures on the back end of the body. Pillbugs do not have these structures and are capable of rolling into a tight ball when disturbed, a behavior that resulted in their common name, "roly-polies."
Isopoda (sowbugs and pillbugs) are terrestrial crustaceans, and are more closely related to lobsters, shrimp and crayfish. They even have gills.
Pillbugs (or Roly Polies) are common backyard inhabitants around the world.
They are called Pillbugs because they can roll into a ball (like an old-fashioned pill) when they are disturbed.
These animals are actually crustaceans, like crabs or lobsters, and just like these underwater crustaceans, they breathe through gills instead of lungs.
The gills, located on the underside of the Pillbug, must be kept slightly moist -- that's why you usually find these animals in damp places.
Look For: Gray, rounded, oval body with shrimp-like body plates; seven pairs of legs. Rolls into a ball when threatened.
Length: 3/8" to 1/2"
Habitat: Under rocks, logs
Life Cycle:
Females lay eggs that they carry in a pouch underneath the body. Eggs hatch into young pillbugs that resemble adults but are smaller. They remain in the pouch up to 2 months after hatching.
Development to adults occurs in about a year and they breed mainly in the spring.
They may live up to 3 years. Up to three broods may be produced annually.
Habitat, Food Source(s), Damage:
Mouthparts are for chewing and rasping. Pillbugs spend bright daylight hours in damp dark habitats such as underneath stones, logs, leaf litter, and other debris.
At night they venture out and feed on decomposing organic material, including mulch and grass clippings. They will feed on the tender foliage, stems and roots of young garden vegetable transplants, seedlings and bedding plants. They also rasp the outer skin of cucumbers laying on the ground in gardens, causing fruit to be deformed and blemished.
Pest Status:
Mainly a nuisance, particularly when they venture indoors; capable of feeding on tender plant tissue and occasionally causing considerable damage to garden transplants and seedlings; medically harmless.

Actually, the real name for them is "Woodlouse"
Woodlice are terrestrial crustaceans with a rigid, segmented, calcareous exoskeleton and fourteen jointed limbs. They form the suborder Oniscidea within the order Isopoda, with over 3000 known species.
Woodlice need moisture because they breathe through gills, called pseudotrachea, and so are usually found in damp, dark places, such as under rocks and logs. They are usually nocturnal and are detritivores, feeding mostly on dead plant matter. They should be considered beneficial garden organisms as they recycle nutrients back into the soil. In artificial environments such as greenhouses where it can be very moist, woodlice may become abundant and damage young plants.
In the United Kingdom there are 37 native or naturalised species ranging in colour and in size (3-30 mm) of which only five are common: Oniscus asellus (the common shiny woodlouse), Porcellio scaber (the common rough woodlouse), Philoscia muscorum (the common striped woodlouse), Trichoniscus pusillus (the common pygmy woodlouse) and Armadillidium vulgare (the common pill bug).
They have a shell-like exoskeleton. As the woodlouse grows, it must progressively shed this shell. The moult takes place in two stages. The back half is lost first, followed two or three days later by the front. Some woodlice are able to roll into a ball-like form when threatened by predators, leaving only their armoured back exposed. This ability explains many of the woodlouse's common names.
A female woodlouse will keep fertilised eggs in a patch on the underside of her body until they hatch into small, pink offspring. The mother then appears to "give birth" to her offspring.

it really is thoroughly widespread. I used to attempt this type project as a baby and that i'm a lady. no human being ever were given onto me or any of the lads that killed insects and worms and issues. I advise that is unlike he's catching the cat on hearth or something. And it isn't even like killing insects will indirectly carry about torturing/killing cats and dogs. you're making a mountain out of a molehill. he will strengthen out of this degree somewhat rapidly. he's usable to appreciate mendacity at this age. that is more suitable useful to not say something more suitable about the caterpillar ordeal. next time problem a lot less about this and take excitement in the actual undeniable actuality that your newborn is playing and exploring nature rather of video games and tv.
