| Arachnids | | Arachnology is the science of arachnids (Arachnida), while Acarology is concerned only with animals with a spider-like appearance. Arachnids belong to the category of Arthropods (Arthropoda) and can be classified as spiders, whip spiders, Solifugae, hooded tickspiders, harvestmen, Acarina and ticks. The largest order within the arachnids are the Acarina. | | |
| | The life span of arachnids, in contrast to that of insects varies widely. Their body growth is greatly limited by a rigid exoskeleton. Arachnids moult, after retreating into hiding and fasting. While most spiders moult hanging down from a thread (thread moulting) to spend the time of moulting on their backs. | | |
| | | Arachnids, in contrast to insects, have 8 instead of 6 legs. Instead of compound eyes arachnids have 8 simple eyes. The head and chest are one unit (prosoma). The prosoma is followed by the abdomen which is not divided and mostly appears in a bigger size. They are a member of the subphylum Chelicerata having the chelicerae – the appendages wh... | | |
| | Forest bug feed by sucking out the insides of fruit. They occasionally kill other insects and suck dead other arthropods (insects, arachnids, crustaceans etc). After mating, the females lay their eggs on top of a leaf. The larvae overwinter - unlike those of other kinds of shield bugs - under the bark of trees, and their further development takes place on broad-leaved trees. | | |
| | In contrast to spiders the head, chest and abdomen form one unit. Harvestmen have neither spinning glands nor poison glands. Like all arachnids they have 8 legs, which in many species are very long and can reach up to 25 times the actual body length. If the Harvestmen is attacked, it can separate from one leg, this misleads its attacker , encouraging it to continue moving away and late... | | |
| | Mites and Ticks | | Mites and ticks, also commonly known as acarina (Acari), are a subclass, in the phylum arthropods (Arthropoda), the subphylum Chelicerata and the class arachnids (Arachnida). Mites and ticks are generally divided into 3 superorders: Acariformes, Parasitiformes and Opilioacariformes. The orders of the Acariformes are: Astigmata, Oribatida, Prostigmata and Sphaerolichida. The orders of the Parasitiformes are: ... | | |
