Do woodlice have a waxy cuticle?
For example, woodlice do not have a waxy cuticle, making them extremely vulnerable to desiccation (Hadley & Quinlan, 1984; Gibbs & Rajpurohit, 2010).
What are woodlice characteristics?
They are flat, oval and uniform grey with a thick, bumpy exoskeleton and have seven body segments, each with a pair of legs. 2 Ocean origins. Though they look like millipedes, woodlice are actually crustaceans, related to shrimps and crabs.
What is unique about woodlice reproduction?
Reproduction. Common rough woodlice reproduce sexually, during warmer spring and summer seasons. Males insert sperm using their copulatory organ, a modification of their abdominal legs. This species is polyandrous; females mate with many males and broods have been shown to have greater than 80% multiple paternity.
Is a woodlice a Myriapod?
Discovering Millipedes, Centipedes, Woodlice & other Isopods in Britain & Ireland. British Myriapod and Isopod Group (BMIG) aims to improve awareness and knowledge of centipedes, millipedes, pauropods & symphylans (the Myriapoda) and woodlice, waterlice & intertidal isopods (the Isopoda) in Britain and Ireland.
What Colour is woodlouse blood?
Oxygen-rich blood of woodlouse is blue-colored. Natural enemies of woodlice are shrews, toads, centipedes, millipedes and spiders.
Do woodlice prefer hot or cold?
Conclusion The results indicated a weak correlation between temperature and woodlice density. They were more abundant in cooler regions of the box. Therefore they seem to prefer cooler temperatures within the range of 21 C-25 C.
Do woodlice have gills?
While most crustaceans live in water, woodlice live on land but breathe through gills like fish. Their gills need to be covered with a thin layer of water to work well, so they prefer to live in places with a lot of moisture. These creatures are found in cool, damp areas, such as under fallen leaves in flowerbeds.
Are woodlice decomposers?
There are many invertebrate decomposers, the most common are worms, flies, millipedes, and sow bugs (woodlice).
Do woodlice have brains?
It’s an oversized, bug-eyed predatory woodlouse that lived half-a-billion years ago – and at the time it was probably the brightest spark on Earth. The primitive arthropod Fuxianhuia protensa is thought to possess the first evidence of a complex brain.
Do woodlice drink water?
How do you let the woodlice drink? Woodlice, like many other insects, get their water from their food. Consider spraying them with water to add moisture.
What temperature do woodlice live in?

What information do you need to know about woodlice?
Information about Wood Lice 1 Description and distribution. A woodlouse is an isopod crustacean. 2 Breeding and dietary information. As for their breeding, female woodlice keep fertilized eggs in a marsupium on the underside of the body until they hatch. 3 Woodlice as pests.
Why do isopods have a waxy cuticle?
As terrestrial isopods don’t have a waxy cuticle, they are susceptible to drying out, particularly the vulnerable young. Research suggests that aggregation is a mechanism of resistance to desiccation, reducing the rate of water loss due to a decrease in the surface area/volume ratio of the group.
Do woodlice lay eggs or give birth?
Breeding and dietary information As for their breeding, female woodlice keep fertilized eggs in a marsupium on the underside of the body until they hatch. At that point, the offspring are called “manca” and have the appearance of tiny (±2mm), white adults curled up in balls.
