Philoponella variabilis? Variable Philoponella

Like all Uloboridae, this species has no venom. They are common in Brisbane gardens but often unnoticed due to their small size. Various specimens are shown here, from different locations. The are all 2-4mm body length. Adult males and females, both with body length about 3-4mm, can sometimes cohabit the same web, as did the last two in these pictures. It is uncertain at this stage which genera these small Uloborids belong to without examining specimens under the microscope and comparing them with diagnostic drawings in published scientific papers. Some may be Uloborus species, such as Uloborus congregabilis.
