Spiders


Tips for submitting spider sightings: 

Photos from various angles are sometimes necessary for specific ID.

  • front (eye arrangement, pedipalp colour)
  • dorsal (above - general colouration, carapace and abdomen patterns)
  • ventral (underneath - especially useful for some of the ground-dwelling families and orb-weaving families)
  • side (further details for general shape, abdomen patterns and eye configuration)
  • back (further details for abdomen pattern).

Comments or photos on the following also provides valuable information if/when such features are applicable and observed...

  • surroundings and location (eg. ground, leaf litter, hand rail, tree trunk)
  • web structure and silk use (eg. orb, messy & tangled, throwing silk)
  • breeding (eg. display, egg sac)
  • behaviour (eg. hunting, interaction, familiarity with people such as the threatening display of a huntsman or the friendly and curious jumping spiders that jump onto the camera lens)
  • notable, unique, exciting or strange observations (eg. spur-like protrusions from legs, camouflage, mimicry)

Please note that the size of the spider is measured by body length.

  • body size is from the top of the cephalothorax (head) to the tip of the abdomen without including the legs.

Thanks Tim - I was expecting the bigger one to prey on the other

Yes female is larger longer spider. Long Jawed spider females may mate with multiple males but the last male to mate is most likely to be successful - so there is an advantage in hanging around in the near vicinity
