Woodlice in general in NZ

One of the main species of woodlice found in New Zealand is genus Porcellio scaber. This species mustiness hit arrived here along with the European settlers during the colonization. Woodlice argon in the main found in damp non- neat areas for example at a lower place bunkum wood, in compost heaps and under rocks. alone woodlice comprise of 3 sections which are fused together. They also have 7 pairs of legs. Woodlice have evolved from the aquatic crustaceans. They belong to the subphylum Crustacea. All woodlice go on through very primitive lungs. Woodlice prefer high humidness and irrigate-cooled temperatures mainly because of the permeability of their exoskeleton to wet and the prejudice of water from their respiratory pleopods. These preferences are behavioral adaptations to help reduce vapour. Woodlice deficiency the waxy cuticle normally found on the exoskeletons of roughly cephalopods. This nub that they are untold more than prone to dry outing up (drying out due to excess water acquittance) than other members of the phylum phylum Arthropoda such as insects and spiders. As a result of this, a lot of their behavior is concerned with avoiding desiccation. The absence of wax or cutin sum that the exoskeleton is permeable to water and so woodlice go out apace preserve in dry conditions. Conversely, in excessively humid conditions it whitethorn be possible for woodlice to absorb water vapor by diffusion through their exoskeleton.

Woodlice have primitive lung-like structures in cardinal of their pleopods. These show up as two white patches on the lower side of their abdomen. The lungs open to the outside via ! a guileless pore; this again means that water loss from their respiratory surfaces is likely to be greater than is the case in virtually insects. Woodlice will try to reduce water loss by moving away from hot and/or dry areas and will therefore tend to congregate in more humid, cooler regions. It...
