Black Widow
(Latrodectus)
Female widow spiders are typically dark brown or a shiny black in colour when they are full grown, usually exhibiting a red or orange hourglass on the ventral surface (underside) of the abdomen; some may have a pair of red spots or have no marking at all.
Brown Recluse Spider
(Loxosceles reclusa)
Adults medium sized, light brown/tan, and with distinct “fiddle” marking on cephalothorax. Eye arrangement distinctive, as 3 pairs (6 eyes total) arranged in a row across front. Venom is “haemolytic”, destroying skin tissues and healing slowly. A “shy” spider which avoids activity, but hides in clothing in closets, furniture, other out of the way places. Up to 50 eggs persac, up to a year to adult, may live several years.
Daddy Long Legs
(Pholcidae)
Extremely long and thin legs with flexible tarsi. They can be distinguished from other long-legged spiders by the arrangment: Pholcidae have two groups of three eyes each, and there may be a pair of small eyes in between them.
Wolf Spider
(Pholcidae)
Wolf spiders resemble nursery web spiders (family Pisauridae), but wolf spiders carry their egg sacs by attaching them to their spinnerets, while the Pisauridae carry their egg sacs with their chelicerae and pedipalps.
Yellow Sac Spider
(Cheiracanthium inclusum)
Very similar to Loxosceles, but eye arrangement very different – 8 eyes (in two row), 4 eyes in top row, 4 eyes in bottom row. Adults light brown/tan, medium sized, with noo mark on cephalothorax. Commonly spin silken retreat in corners and ceilings, and spend days in these. Do not spin webs for prey capture. Venom similar to Loxosceles, but symptoms not nearly severe.
