Caused By:-     Several Genus and species of Crustaceans


Woodlice are crustaceans related to slaters, shrimps, lobsters and crabs, and belong to the order Isopoda of arthropods. They are the only crustaceans that have properly invaded land, without the need to return to water in order to breed, but they are restricted to fairly damp places because they breathe through gills. They have many common names which include armadillo bug, doodlebug, pill bug, roly-poly, and potato bug. They are found around the world in many Genus and over 3000 species. They all look similar with most being flat oval creatures up to 15 mm long, grey or brown segmented, articulated shell or exoskeleton. The head is quite small with a pair of angled antennae and they have 7 pairs of legs. They are nocturnal and feed at night on rotting wood, fruits and other decaying vegetable matter. They do not attack healthy plants, but may attack young seedlings and are quite harmless. They do not spread disease, but might carry fungal spores from one place to another. They are best ignored as they provide a great service in recycling fallen plant tissues. Picture from Wikimedia Commons.


The woodlice is preyed upon by a number of animals around the world which include Toads, Centipedes, Spiders, Millipedes and wasp. They will be killed by insecticides.
