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.

Will look into your suggestion @Hejor1 ! What's known of their range is suspected to be driven by human transport (Hurni-Cranston & Hill, 2021) so it could be a possibility.

Cosmophasis sp. (genus)

I remember talking about E. splendens somewhere on Naturemapr a while back, the species is misplaced in the genus Euryopis and should be transferred to Steatoda. The spider here is a true Euryopis :)
