Jumping spiders (Salticidae)
are the personalities of the spider world. Though generally
small in size (up to 12 mm body length), their large eyes,
prodigious jumping ability, often brilliant colours and cocky,
inquisitive activity make them very appealing. Many are daylight
hunters, using their excellent vision to track, stalk and
calculate distance, before suddenly leaping on their prey,
propelled by their strong back legs. Males are often more
strikingly coloured, patterned or adorned with leg or body hair
tufts than are females. They use these adornments to impress the
females during often elaborate courtship displays. Information -

Spider A (2pics) - from Ed's page I think genus Simaethula. First seen perched
on a daisy bud, it jumped to the ground, crossed a path and climbed up this
blade of grass. Seen only the once - tiny at 3-4mm. (NB: My size estimation
skills are limited - bear this in mind when reading all comments which follow.) |

|
Spider B (1pic) & Spider C (3pics) - both very small, less than 5mm. Both
kept mainly to the sand but one C did jump up onto a low sleeper retaining
wall. B was seen only the once, but there are several Cs about in my yard.
Given the obvious similarity of form, they may both be genus Zenodorus,
and, from Ed's page, C may be Zenodorus orbiculatus. |

Spider C - could be
Zenodorus orbiculatu?? |

Spider D (3pics) - from Ed's page, either genus Sandalodes, Ocrisiona ZZ275,
or Frigga. There are quite a few of these in my Callistemons, and I've recently
seen one in a Melaleuca quinquinervia (paperbark). They vary in size (is
this age/sex based or have I a mix of the above genera?) from 5-6mm up to
perhaps 12mm. I see them regularly sunning themselves or dining out on low
branches, like this one. |

|
Spider E (2pics) - from the web, perhaps
Helpis sp. Several of these. They
hang out on the windows of my house. They tolerate fairly close approaches
though can get a bit agitated if one persists too long. Body perhaps just
over 10mm long.
|
 |
 |
| .. |
|
Spider F (2pics) - similar to E, so perhaps Helpis sp. A couple of these.
More wide-ranging than the similar E, they wander the walls of my house,
the paths, or the super six fencing. Like E, they tolerate fairly close
approaches though can get a bit agitated if one persists too long. Body
perhaps just over 10mm long. |
|
 |
 |
| .. |
|
Spider G (1pic) - Seen only once on super six fencing. I initially thought
it was an F, but it obviously is not. Size similar to E and F. |
 |
| .. |
|
Spider H (3pics) - at least two known. One haunts the space between the
glass and flywire of my loungeroom window - its badge is yellowish. That
part of the house's exterior is sheltered - photo ops very limited and obviously
not unobstructed. The second hangs out on the brickwork near my back door,
and only recently got daring enough to come down to doorknob level and lower
- its badge, shown here, is off-white. This spider is also about 10mm long. |

Spider I (1pic) - from Ed's page, Opisthoncus sp. (perhaps
parcedentatus)
A lovely little spider, perhaps just under 10mm long, dislodged from shrubbery,
as was the next... |
 |
| .. |
|
Spider J (1pic) - from Ed's page Lycidas
Scutulatus. Another pretty spider,
about the same size as spider I. |
 |
| .. |
|
Spider K (3pics) - from Ed's page genus Myrmarachne. So far seen only on
Acacias. I think I have both sexes here, though which is which I'm uncertain.
This ant mimicking spider is possibly 10mm long. |

Spider L (3pics) -
Sandalodes superbus
- the largest of my sightings at perhaps
15+ mm. I've only seen the one spider, which lives under the loose bark
which has peeled off to the base of a Coastal Moort. It's okay until it
becomes aware of me, then vanishes for the rest of the day. Because it orients
itself vertically on the bark, and generally faces down, I have been unable
to properly catch its eyes. |

|
Spider M (3pics) - from Ed's page, perhaps genus
Holoplatys - and, from the
web, aka. Sandalodes scopifer or Ocrisiona leucocomis. This spider lives
under loose bark at the base of a big eucalypt. Quite wary, but has given
me some chances. I'm not sure there isn't more than one of these, but, to
date I have never seen two at the same time. Maybe 10-12mm in length. |
 |
 |

|
| .. |
|
Spider N (3 pics) - from Ed's page, perhaps genus
Damoetas. Lives in very
close proximity to Spider M. It's only 5-7mm long, yet I've seen it and
M only centimetres apart, with the smaller showing no fear of being eaten,
and the larger no interest in so partaking. |
 |

|
Spider O (3pic) - from Ed's page, Opisthoncus sp. Very like Spider I. At
just under 10mm long, and dislodged from a eucalypt, I wouldn't be surprised
if it was the other's complementary sex. Apologies for the harshness due
to poor lighting. |
 |
 |
 |
| .. |
|
Spider P (1 pic) - Approx 10mm long, this spider crossed my path after I
had some work done on some trees badly affected by Perth's recent (2010-11)
long dry spell. I have not seen the spider since. |
 |
| .. |
|
Spider Q (2 pics) - Another likely refugee from the same disturbance. Another
single sighting. Another one about 10mm long. |
 |
 |
| .. |
|
Spider R (2 pics) - from Ed's page, possibly Lycidas sp. This one was perhaps
9-10mm long. If not Lycidas sp., it is perhaps an Opisthoncus sp., though
I've few grounds for that opinion. |
|
 |
 |
| .. |
|
Spider S (2 pics) - Another medium sized jumper, around 8-10mm in length.
It looks very much like an unidentified species I found in another website
recently. |
 |
 |
| .. |
|
Spider T (1 pic) - Very much like the Helpis sp. appearing in this page,
though this one was much smaller, at perhaps 5-6mm. As a guide, the greyish
'road' it is facing is the standard mortar width between courses of bricks. |
 |
| .. |
|
Spider U (2 pics) - Very small, at perhaps 2-3mm. This tiny spider was found
on a strip of newly fallen bark shed by a recently drought killed eucalypt.
On that same tree was a Holoplatys sp. (Spider M) and under it, also on
a bit of bark, was Spider V (next). |
 |
 |
| .. |
|
Spider V (2 pics) - Very small, probably exaggerated even at 2mm. As mentioned
above, it was found on a bit of bark shed by a recent drought victim. The
longitudinal white stripe on its back is a true colour feature, not a reflection
like the other larger white patches, and its palps seemed a brighter green
through the viewfinder - perhaps the flash washed them out a bit. Pity,
I recall it as more striking than it appears here. |
