Orb web spider sketch | Limited edition fine art print from an original drawing. My sketches start life as hand-drawn graphite images made on cartridge paper. I often work on these with charcoal, oil pastel or Caran d'Ache to create the look I'm after. The artwork is then scanned and finessed digitally ready for fine art printing. This process often referred to as Giclée printing uses the highest standard of printing methods to give gallery quality results that maintain all the details of the original sketch. The graphite pencils I use are Faber-Castel, the oil pastels are Sennelier and the china-graph is Caran d’Ache. The inks are pigment based archive quality (100years+). The heavyweight specialist papers I use are of the best professional quality having a wonderful surface designed specifically for fine art drawings and illustrations. Very limited editions with only ten per size printed. All artwork is signed and includes a certificate of authenticity. The A5 are 5.8" x 8.25" (14.8cm x 21cm) The A4 are 8.25" x 11.7" (21cm x 29.8cm) The A3 are 11.7" x 16.5" (29.8 cm x 42cm) The A2 are 16.5" x 23.4" (42 cm x 59.4cm) Frames not included in price. Free shipping on artwork to UK destinations.

An orb weaver spun a large and beautiful web between a bush and my car! It’s a good thing I had the flash(light) on my phone, because I would have walked right into it in the dark. Sadly, I had to ruin the web because I needed to actually use my car, but I made sure to relocate the spider to a safe location before doing so. #spider #orbweaver #orbweb #spiderweb https://www.instagram.com/p/B0fqbrvF8yB/?igshid=1rx4oksgvj3an

Spider praying upon the dragonfly 網に白帯(はくたい)が目立つことからコガネグモであることがすぐに分かる。白帯の機能については諸説あるが、飛翔能力も視力も優れたトンボさえ囚われてしまうことから、獲物を誘引するとの説に賛成したい。従って、隠れ帯と呼ぶことはしない。 #Argiope_amoena #Argiope #spider #コガネグモ #webdecoration #stabilimentum #orbweb #spider #白帯(はくたい) #スタビリメンタム #Uloboridae #ウズグモ科 (総社緑地) https://www.instagram.com/p/CF32v6UgO76/?igshid=e3125y1lwlub

🕷Arañas de rayas blancas🕷 🕸Orchard Orb-weaver🕸 📚Genus Leucauge📚 . These beautiful spiders can be found in the tropics around the world, usually in riparian habitats (habitats between the land and a river or stream) of the rainforest above creeks or other bodies of water inside the forest. Sexual dimorphism is present in the species. 🌎🌍🌏 . You can distinguish them by their six black eyes in the front and their multicolor opisthosoma (their abdomen). 🍭6️⃣👁 . They build two types of nets, one as a barrier web, which has no patterns plus utilized for protection, and the main orb-web, which used to hunt their prey.🦋🐞🐛🦟🦗 . ➡️Reference: http://www.americanarachnology.org/JoA_free/JoA_v38_n3/arac-38-03-446.pdf . . . #spider #artopodos #forest #panama #pty #environment #naturaleza #animal #arthopods #science #orbweb #discover #wildlife #amazing #canon #macro #water #arachnid #rest #love #cool #photography #photo #bosque #rios #arañas #biologia #biology #onlynature 💚 (at Distrito de Chepo) https://www.instagram.com/p/B-TEs_eBxBs/?igshid=1fea9ph2kyuoi

a few months back there was a spider that lived in the crack between my wall and my floor (I have a very poorly made apartment) and he didn't weave any webs or anything he just sat there. I'm wondering if there are other spiders with that kind of behavior? it was really fascinating to me

There are a lot of spiders that don't make cobwebs or orbwebs, including huntsman spiders and jumping spiders. Instead of waiting for prey to come to them, they hunt actively.

[ms-hells-bells]

but anyway, in terms of the spiders, i just can’t figure out what species they are. they’re obviously not jumping spiders. my best theory at why they’re covering the whole area in web is that they (perhaps juveniles) were brought over by the massive wind storms we’ve had recently. especially since young spiders ‘balloon’, where they release a thread of silk and let the wind take them wherever in order to have a new area with less competition. and several spider species have either autumn mating seasons (in fact, most spider species have babies around autumn) or autumn maturation (when some species start making webs), and so if the wind coincided with a boom in that spider population, and the wind was unidirectional, then it makes sense that they have all ended up here, perhaps even further away than they would have normally landed. 

i theorised baby orbwebs, because they are creating the classic ‘orb’ cobweb, but orbwebs only create webs once they are mature, so no. i looked at a few other spiders, but i still have no clue. not grass spiders, they create funnels. only thing remaining i can think of is that they may be baby house spiders that got blown away and couldn’t land to get into houses, so ended up here. meaning most of them will likely die outside, but yeah. this is driving me nuts trying ot figure this out.

Much like our previous spider post, the spider under the spotlight today (Leucauge dromedaria) is an Australian import that we found on one of our bush walks here in New Zealand. Its common names are ‘Horizontal Orbweb Spider’, ‘Silver Orb Spider’ and ‘Humped Silver Orb Spider’.

The first described specimen was misidentified by Koch in 1872 as a different northern Australian species (Leucauge granulata, the Roughened Silver Orb spider). Later in 1988, Davies (PDF) also misidentified the species. This is understandable as they are similar looking.

Appearance

This spider is relatively small being an average of 10 mm in length. The males are smaller than the females, as is the case with many spiders.* They have silver abdomens with black and yellow markings. Their leg colouration is generally a translucent yellow through blue with black bands. Their cephlothorax is normally buff-brown/orange to white.

Location

This spider is generally found hanging from its horizontal web over damp ground. We found ours near a marshy area at Gordon Park Scenic Reserve, Whanagnui.

In New Zealand, these spider can be found across the North Island and at the top of the South Island. As for Australia, iNaturalist sightings show that they have been found on the east of lower Queensland and on the eastern parts of New South Wales. Archne.org.au explain the spider can be found ranging from Maryborough, Queensland south to Tasmania and New Zealand.

Behaviour and Adaptations

The Silver Orb Spider creates horizontal orb-webs from which it hangs. The spider’s silvery back faces towards the ground. This is the perfect camouflage as from beneath their web, their silvery body is easily lost against the bright sky. But, from above, their dark underside camouflages them against the dark foliage or soil.

They target flying insects as prey that are landing or ascending from plants and water surfaces found beneath their webs. Their diet consists of small insects such as moths, bugs, flies and beetles.

When disturbed the spiders drop instantly to the ground which makes getting close for a photograph particularly difficult!

*Interestingly, male spiders are often smaller than females due to the selection pressures associated with their dimorphic sexual behaviour. Males need to travel distances to find females. Many spiders utilise ‘Bridging’. This is an unusual mode of getting across large gaps in foliage. Researchers have shown that a spider’s ability to utilise the wind to carry a strand of web to their destination and then climb upside down along the resulting bridge, is associated with smaller size. Females are larger because this confers an advantage in generating offspring.
