[3] The end of the dark part of the ventral side of the abdomen contains some white spots; the spiderlings also have a much lighter colour on their legs compared to when they are an adult.

When the spiderlings grow to a total length of about 2.5mm, Salsa fuliginata females will have a squared shape at the anterior of the carapace and the posterior of the abdomen will be slightly angled.

[3] The carapaces of females are brownish at this size similar to males and both sexes' pattern on their abdomen bear a resemblance of an adult Salsa fuliginata.

[5] Terminal apophysis have overall rectangular shape with a projection at the tip which looks like a thumb; conductor is weakly sclerotised and flat; embolus of the male is straight, lengthen and also pronounced.

Sexual dimorphism exists in Salsa fuliginata, where the females are generally larger than the male like most spiders.

[5] S. fuliginata females have total lengths ranging from 4.5-11.0 mm based on 30 specimens from two research studies (Dondale[3] and Framenau & Pedro[5]).

It was introduced to New Zealand over 22 years ago, where it is found in Christchurch, Auckland, Wellington, and near Lake Taupō in the North Island.

Because Australia and New Zealand are temperate countries, the spiders' mating and egg laying happens during spring and may continue over summer.

[12] Based on Framenau & Pedro,[5] Salsa fuliginata mature adults are common and mostly collected ranging from October and January.

They tend to feed on small insects such as flies, moths, and beetles captured in the webs that they construct.

[13] According to Keziah D'Souza, a masters student in University of Auckland, one of the species that prey on Salsa fulignata is Pison spinolae, which is more commonly known as the mason wasp.
