Now, I know these wondrous creatures may not be everyone’s cup of tea but I’m going to write a blog on them anyway and try and convince you that they’re not that bad, and not only that, that they are specimens worthy of a moment of your time to admire.
Let’s begin with their craftsmanship. Spiderwebs often stand out as some of the most stunning creations in nature. Just take a moment to observe them against the backdrop of the grasslands, where the golden rays of the setting sun illuminate their intricate patterns, or in the early morning when dew collects on each delicate strand, transforming them into glistening masterpieces.
Spider silk, often hailed as one of nature’s marvels, holds secrets to strength and adaptability that fascinate scientists and enthusiasts alike. Imagine a rope under tension, its fibres tightening and compressing towards the centre as the strands of the weave resist straightening. This compression, a key component of rope strength, is absent in spider silk. Unlike woven ropes, spiders spin single strands of silk, each capable of bearing incredible loads relative to its thickness, the strength lying not in woven complexity but in its singular, robust strands. Along with this incredible solid strand strength, spider silk exhibits elastic/plastic properties. Unlike traditional elastic materials, which rebound when stretched, spider silk deforms permanently, stretching and holding its shape. This characteristic plays a crucial role in the spider’s hunting strategy. When prey collides with the web, the silk deforms outward, ensnaring the victim instead of rebounding and potentially allowing escape.
And now let’s ease into the admiration of the creatures themselves, starting with their locomotion. By contracting muscles in their cephalothorax, spiders force hemolymph into their legs, providing hydraulic pressure that, combined with tendon systems, facilitates movement. Jumping spiders, for instance, propel themselves by rapidly expanding their legs with hemolymph, enabling impressive leaps of up to 50 times their body length. Just think this through, and try to envision it; the complexity of the miniature arrangements inside of these arachnids is incredible!
A spider that most can appreciate the beauty of are the orb spiders, also known as the banded-legged nephilia. They’re slightly venomous but very reluctant to bite and do so only if severely provoked. I say most can appreciate these because they make no effort to conceal themselves, creating massive beautiful golden webs that are easily seen and avoided (or as you may be catching onto the theme here, admired). These spiders stand out for their remarkable silk production and intricate behaviours. The name “nephilia” originates from ancient Greek, meaning “fond of spinning,” a fitting tribute to the colossal webs these spiders create, which can endure for years.
The silk spun by Golden orb spiders is exceptionally strong, with claims suggesting that if those strands were as thick as a pencil, a Boeing 747 could fly into that web and be trapped whilst flying at maximum speed! What?! That’s crazy. These webs serve as effective traps for insects and even small birds, showcasing the unparalleled strength and durability of spider silk.
Female golden orb spiders exhibit meticulous behaviour in web maintenance. They designate specific sections of their webs as “pantries,” where they store future meals or potential bait for fresh prey. These food items are neatly arranged and wrapped in silk to prevent dehydration, demonstrating the spiders’ resourcefulness and attention to detail.
In the realm of golden orb spiders, females reign supreme. They are often up to ten times larger than their male counterparts and take on the responsibility of web construction. Male spiders typically inhabit the females’ webs, enjoying the comforts of food and shelter. When seeking to mate, males employ cautious tactics, tapping on the web’s edge to gauge the female’s mood or offering snacks as a distraction before hastily depositing their semen and making a swift exit; not exactly an amorous affair, but ultimately it’s about gene propagation, not love, out here in the wild.
And that concludes my attempt at convincing the many arachnophobes (a very understandable fear) out there to give spiders a chance. They’re not so bad, once you get to know them.
Web spiders are a favourite subject for photography, I took one myself like the first in the list. All spiders are so necessary and incredibly diverse. I hope they will be helped to thrive as well as other invertebrates and pollinators, they are becoming increasingly rare….
A great blog, thanks Kyle.
thank you for sharing this!
Kyle, thanks for your look at the arachnophobes of Londolozi. They are a necessary and very adaptable species. Not sure that I have a favorite but their webs are fascinating to observe.
I asked for a bug blog and Woohoo, I got one! Thanks so much. When I’m swatting flies in my house (I don’t use pesticides at all) I try stun them rather than kill them. I then take them outside and gently put them on a web outside. So long as there are one or 2 legs still moving, the spider gets a good meal.
Scrolling ever so slowly to avoid surprises, I appreciate the not-so-scary pics! I am one of those spider haters, BUT I do appreciate them and will always relocate (unless too big then the house must be burned down…one reason I could never live in Australia)! I DO love the little jumping spiders however, for the same reason as you…too cute!
Well, you convinced me to admire them but I’m still not enthused about being close to them or having one over to dinner! A ranger (not Londolozi) once tried to put a golden orb on my arm and I’ve had PTSD ever since!
Kyle, I am one of those arachnophobes people. Terrified of spiders and will rather face a snake than a spider. We moved to a nature reserve two years ago, saying the least I had to speak hard to myself for not getting upset and fearful everytime I saw a spider in my house. I even had one climb on my arm at 2:30 in the morning. I off course freaked out and jumped out of bed, to waking my husband up to kill this spider. Terrifying experience I still get
Well Kyle, you’ve taken the somewhat scary world of arachnids and through your words and photos, made them beautiful and fascinating. I’ve always loved and been intrigued by spider webs, marveling at their designs and inherent strength. I do find the Golden Orb spider exciting to spot during the drive, and especially if it’s in there with newly caught prey.
They really are fascinating creatures. I particularly love your photo of the jumping spider – great macro photography.
Love this post about spiders. They are often demonized in captivity as well as the wild, and your post demonstrates their brilliant natural resourcefulness!
We need predators to keep nature in balance and the spiders are no different. I always catch and release any that find their way into our house.
Great blog on spiders, Kyle.
I admire their intricate webs and their way of surviving. But I still wouldn’t like to have any of them – at least not the bigger ones or poisonous ones -in my room or tent.
In the wilderness they are really fascinating.
