Our Bugs's Life #11 - Conversations with the Bugman Part 4


All photos by me, Ridou Ridou - and all the great answers to my questions about bugs in our 
garden and home by the great 'Bugman' (

Hi again, I thought of checking out how many posts you’ve got on St. Andrew’s Cross Spiders, and was surprised to see 
only one (from Singapore). They are very common at our place, so I thought of taking some fresh photos of them for your 
site, but came across another spider that I haven’t seen before here, and took photos of it. So, I’m sending you a couple 
of older images that I’ve taken of the St. Andrews. Hope you can use them.

St. Andrew's Cross Spider

Hi Ridou,
Thanks for the excellent images.  We believe we had additional images of St. Andrew’s Cross Spiders, Argiope 
keyserlingi, and they might have gotten lost when we did a website migration last year.  We may check our old computer 
for the posts.  The Brisbane Insect website has nice images and helpful information on this species.

Hi Bugman, here are a couple of photos of a species of spiders I don’t remember seeing at our Sydney backyard before. 
Would you be able to id it, please.

Golden Silk Spider

Goodness gracious Ridou, you are keeping us busy,
This beauty is a female Golden Silk Spider in the genus Nephila.  There are numerous species in Australia, and we are 
not certain exactly what species this is.  The Spiders of Australia website has several identified and unidentified 
members of the genus.  We believe this might be Nephila ornata based on images posted on the Nature Stuff website.

The Brisbane Insect website has nice images of several other members in the genus.

Hi again,
I quite like this small ‘two-headed green frog spider’ I found inside our house. Would you be able to identify it?

Crab Spider

Hi again Ridou,
This is a Crab Spider in the family Thomisidae, and there are several species pictured on the Brisbane Insect Website.  
We are uncertain as to what species you have submitted, and part of our confusion arises from the variability of many 
species.  One North American species known as the Goldenrod Crab Spider, Misumena vatia, is known to be able to 
change its coloration based on the color of the flower or plant upon which it prowls for prey.  You can see some of these 
variations on BugGuide.  Crab Spiders are easily identified because the two pairs of front legs are considerably longer 
than the two pairs of hind legs.  We found many nice images of Crab Spiders on the Save Our Waterways website, and 
there is where we believe we matched your spider to Sidymella rubrosignata.  An image on Wikipedia supports that
