 +===== BITES =====
 +
 +For a spider bite to be regarded as a definite bite (by a particular type of spider), all of the following must occur:
 +
 +  * Evidence of a bite: clinical effects at the time or soon after the bite, including discomfort or pain;
 +  * Collection of the spider at the time or immediately after the bite;
 +  * Identification of the spider by an expert arachnologist.
 +
 +Discomfort or pain always occurs with spider bites; their absence goes against the diagnosis. Other important local effects include:
 +
 +  * Fang marks/​bleeding are indicative of fang size and so the size of the spider;
 +  * Erythaema/​red mark;
 +  * Itchiness (immediate or delayed);
 +  * Swelling/​oedema is uncommon.
 +
 +Over 80% of bites are caused by 6 major families of spiders:
 +
 +  * Orb weavers (//​Araneidae// ​ )
 +  * Huntsmen (//​Sparassidae// ​ )
 +  * White-tail spiders (//​Lamponidae// ​ ://​Lampona// ​ spp.)
 +  * Redback spiders (//​Latrodectus hasselti//) and cupboard spiders (//​Theridiidae// ​ )
 +  * Wolf spiders (//​Lycosidae// ​ )
 +  * Jumping spiders (//​Salticidae// ​ )
 +
 +The majority of cases of bites involving these spiders result in local pain alone. Systemic effects are rare and mild.
