A juvenile spider?

This spider was given its common name because it sometimes curls the end of its abdomen upwards in much the same way as a scorpion does. It usually rests on a strongly anchored silk thread at the end of a string of masses of insect debris and sometimes egg sacs as well. The web has the conventional orb shape of araneids.

There is some uncertainly as to whether the red spider included on this page is an immature version of the yellow-brown adult or is actually a different species. However, it should be noted that the red specimen shown here was of adult length and also had a mature epigynum, which suggests it may be a different species or sub-species.

Spider(s) with a very similar appearance: None.
