By the end, you’ll appreciate how trapdoor spiders play an important role in their ecosystems. Let’s crack open the trapdoor on the world of these awesome arachnids!
What are Trapdoor Spiders?
Trapdoor spiders are the secret ninjas of the arachnid (that’s the proper name for spiders, you know! )world who build incredible underground homes! There are over 40 different species of these sneaky spiders across the planet.
Would you believe trapdoor spiders have been around since dinosaur times? It’s true! Fossils show their ancient ancestors were crafting underground burrows with trapdoors millions of years ago when T-Rex and Triceratops roamed the Earth!
These spiders are clever ambush predators who patiently wait in their burrows for a snack to walk by above. When they sense vibrations from an unsuspecting insect or critter, they burst out in a flash and snatch their next victim!
Their awesome camouflaged trapdoors help them hide from predators, too. These spiders are often mistaken for Funnel-web spiders.
Some trapdoor spiders can live in their underground burrows for up to 20 years! They don’t build fancy webs above ground like other spiders.
Instead, they use their house designing skills to engineer hidden underground houses to keep them safe and provide yummy bugs to eat! Trapdoor spiders really are the coolest secret underground builders in the arachnid world!
The Super Clever Trapdoor Home
A trapdoor spider’s burrow is like a secret underground house equipped with everything they need! They dig deep tunnels using their powerful legs and jaws. Some burrows go over 3 feet straight down into the ground!
At the surface, the spiders use soil, small rocks, vegetation and silk to disguise the entrance. This camouflaged trapdoor blends in perfectly with the ground around it.
The hinged door acts like a drawbridge to their castle. The spiders latch the door shut with more silk when they’re home, and unlatch it to leap out when they sense food. Some species add extra security with a branch or leaves above the door to hide it even more!
Inside, the burrow opens up into a silk-lined bedroom where the spider sleeps and waits for prey. Some spiders build side tunnels off the main shaft with multiple trapdoors leading to the surface. It’s like a secret spider mansion underground!
With their architect and engineer skills, trapdoor spiders build the ultimate hidden home to keep them safe and fed. They are truly the underground architects of the arachnid world!
What do Trapdoor Spiders Look Like?
Trapdoor spiders size
Trapdoor spiders come in a variety of shapes, sizes and colours. Most range from 1-2 inches long, about the size of a golf ball, but some species can grow up to 2.5 inches long – as big as a tennis ball!
Their bodies are hairy, fuzzy and plump, often patterned with camouflaging spots, stripes or mottled colours like brown, black, gold and cream. This helps them blend in against soil and bark when hiding out in their burrows.
They have eight eyes, like most spiders, with two large main eyes in the middle and six smaller eyes surrounding them. This gives them great all-around vision to spot prey and predators.
Trapdoor spiders have two main body sections. Their large abdomen houses their organs and silk-producing spinnerets. Their head or if you want to know the big proper name for it, its “cephalothorax”, Can you say that!? It contains eyes, jaws, legs and mouth.
Speaking of jaws – trapdoor spider jaws are massive! They swing their giant black jaws open wide to bite into prey.
Their eight spindly legs allow them to crawl through their burrows with ease and sense the faintest footsteps above their trapdoor. Trapdoor spiders may look a little scary, but their cool colours, big eyes and fuzzy bodies make them one of the most unique and interesting arachnids out there!
Spikes and Hairy Bodies
One of the most distinctive features of trapdoor spiders are the spikes and hairs covering their bodies. Most species have a spiny armour of stiff, thick hairs called setae on their backs and abdomen.
This spikey coat provides protection from predators trying to crack through their super hardened exoskeleton. It also helps keeping them warm and snuggly by holding in heat and moisture beneath the hairs, which is helpful in the spiders’ underground burrows.
Their legs and mouths are covered in tiny sensory hairs that help detect the slightest vibrations from above ground. Prey moving on the surface tickles these sensitive hairs, alerting the spider that a potential meal is near!
While all that hair may look scary, it serves an essential purpose for the spiders’ survival and skill as stealthy ambush hunters. The next time you see a fuzzy trapdoor spider, you’ll know its hairy spikes are helping keep it safe in its underground lair!
Jaws and Venom, Are Trapdoor Spiders Poisonous?
Trapdoor spiders have large, powerful jaws called chelicerae that swing open 180 degrees, which is REALLY WIDE! They use their mighty jaws to latch onto prey and pump in venom. But are trapdoor spiders poisonous?
Their venom is toxic to small insects and animals but not considered dangerous to humans. The venom from a trapdoor spider bite causes mild swelling, numbness and pain around the bite but is not lethal.
While the venom isn’t very potent, their jaws pack a powerful pinch. Trapdoor spiders should be handled gently and with care. One unique species called the African trapdoor spider has jaws large enough to puncture a child’s finger, so watch out kiddies!
So yeah! – trapdoor spiders are venomous to small prey they eat but are not to us humans. Their venom is mild compared to other spider species, but their big jaws can really deliver a nip! It’s best to observe these cool spiders from a distance.
Where You Can Find Trapdoor Spiders
Trapdoor spiders burrow into soil all over the world except Antarctica! These sneaky spiders build underground lairs on every continent.
In North America, you can find trapdoor spiders burrowing across the southern United States, down through Central America and all over the Caribbean islands. The cool California trapdoor spider lives in sunny burrows up and down the West Coast.
South America is home to trapdoor spiders in Chile, Argentina, the Amazon rainforests, and other tropical places. Africa has colourful rainbow trapdoor spiders and the giant African trapdoor spider with massive jaws.
Australia has over a dozen unique trapdoor spiders digging intricate burrows. One rare spider called the Tasmanian cave spider only lives in a few caves in Tasmania! In Europe and Asia, trapdoor spiders hide out in forest floors from Spain all the way to China.
So, no matter where you live, keep an eye out for trapdoor spider burrows! You never know when you might discover the hidden underground world of one of these sneaky arachnids.
Trapdoor Spiders Have Super Senses for Ambush Attacks!
Trapdoor spiders don’t catch their food by spinning fancy webs like other arachnids. Instead, they use their super spider senses to detect prey and launch ambush attacks!
These sneaky spiders can feel even the tiniest footsteps above their burrow using sensitive hairs on their legs and bodies. As soon as they sense something yummy, like a beetle or cricket crawling above, they unlatch their trapdoor and BAM! They leap out and snatch the unsuspecting prey in their spiky jaws.
The trapdoor spider’s secret weapons are their patience, speedy reflexes, and ability to camouflage themselves inside their burrow. They will wait absolutely still for hours, days, or even weeks for the perfect meal to walk over their trapdoor. Talk about determination!
Fun experiment!
You can test your own senses just like a trapdoor spider with this fun experiment:
1. Get an adult to help poke small holes in the bottom of a paper cup.
2. Cover the holes with tape so nothing falls out.
3. Put a coin or other small object inside the cup.
4. Place the cup upside down on a table.
5. Lift the cup up quickly to hear the object rattle inside!
This shows how vibrations travel through objects – just like how trapdoor spiders use vibrations to find their prey! They have pretty cool spider senses.
What do trapdoor spiders eat?
The Trapdoor Spider’s Diet – Bugs, Bugs, and More Bugs!
Trapdoor spiders may have a ferocious ambush attack, but they mostly use their skills to munch on small insects and invertebrates. A trapdoor spider’s diet consists mainly of bugs, bugs, and more bugs!
Some of their favourite meals include crickets, grasshoppers, beetles, centipedes, millipedes, roaches, and other crawling insects. Basically, anything small enough for them to overpower makes for a tasty treat.
Trapdoor spiders don’t spin normal webs to catch prey. Their webbing is used to build their burrows and trapdoors. So they rely on their stealthy ambush strategy instead.
The spiders will also occasionally eat soft-bodied critters like frogs, snails, slugs, worms, or even small lizards if they can grab them. But most of the time, these arachnids patiently wait underground to munch on any juicy bug that passes by their trapdoor.
While trapdoor spiders play an important role in controlling pest insect populations, they pose no threat to humans, plants or larger animals. They just want to nibble on bugs in peace from the comfort of their underground lairs!
A Day in the Life of a Trapdoor Spider
What does an average day look like for a trapdoor spider? Their daily routine is pretty simple – hang out underground, wait for food, pounce on prey!
In the daytime, trapdoor spiders are typically hunkered down in their burrows avoiding the hot sun. They spend their time grooming their legs, reinforcing their silk trapdoor, and resting up for the night hunt.
When the sun starts to set, it’s go time! The spiders will unlatch their trapdoors and wait with their legs outstretched, using those incredible senses to feel for any vibrations from wandering insects.
If something juicy comes along, like a moth or beetle, SNAP! The trapdoor spider leaps out in a blur and snags its prey with its mighty jaws. After dragging the meal down to its lair, the spider will munch away on its reward.
If no prey shows up, the spider retreats back into its burrow to wait patiently for another night. Trapdoor spiders are happy to hide in their underground bunkers for days or weeks, conserving energy until their next ambush.
So, while they may not seem active to us, trapdoor spiders live very full lives hunting bugs, spinning silk, and hanging out in their hand-built earthen homes. Just another day in the life of a stealthy underground arachnid!
A Trapdoor Spider’s Friends and Foes
Predators – The Enemies of Trap door Spiders
Trapdoor spiders may seem well-defended in their underground fortresses, but they still have to watch out for predators! Some enemies of trapdoor spiders include:
- Centipedes – These quick creepy crawlies will invade the spider’s burrow looking for a meal.
- Wasps – Wasps, like tarantula hawks will try to sting and paralyse trapdoor spiders to take back to their nests.
- Snakes – Snakes will slide into burrows looking for a juicy spider snack.
- Hyenas and Meerkats – These savvy animals will dig up burrows to grab spiders.
- Birds – Birds like shrikes will snatch spiders basking outside their burrows.
- Parasitic wasps and flies – The only critters that can get through the trap door spiders front door!
To stay safe, trapdoor spiders rely on their camouflage, armour of spiky hairs, and speedy ambush attacks!
Lock that trapdoor!
Trapdoor spiders have a clever trick for keeping their bunker doors shut tight. When predators come knocking, the spiders use their mighty jaws to hold the lid closed. At the same time, they brace their long, spindly legs against the burrow walls for extra lockdown power!
This spider security system stops most enemies in their tracks. But watch out for sneaky parasitic wasps – they’ll chew right through the trapdoor! These wasps don’t care about a simple locked door when they’re hungry for spider. Keeping out pests takes some serious spider strength and smarts in the trapdoor world.
Prey – What Trapdoor Spiders Love to Eat
While trapdoor spiders have scary enemies, they love munching on their favourite prey:
- Crickets and Grasshoppers – Nothing like crunchy insects for dinner!
- Beetles and Earwigs – Trapdoor spiders think beetles and earwigs make the perfect meal.
- Roaches and Centipedes – Roaches and centipedes that wander too close to the burrow get snatched.
- Moths and Butterflies – If a juicy moth comes by, the spider will leap for the capture!
- Small Lizards and Frogs – Occasionally, they’ll eat a small vertebrate critter too.
Trapdoor spiders may have dangerous foes, but their burrows help them safely feast on many kinds of small prey!
Life Cycle and Reproduction
Egg Sacs and Little Baby Spiders
Once they’re grown up, female trapdoor spiders are ready to lay eggs and start the life cycle again. The mama spiders craft round, silky egg sacs and fill them with up to 40 eggs. She carries this bundle under her belly.
When the eggs hatch, tiny baby spiders look just like mini mom and dad! The mama keeps her babies safe in the burrow, letting them ride around on her back until they shed their exoskeletons for the first time.
After a few weeks, the young spiders leave the burrow to dig their own little homes nearby. And the life cycle starts over!
Lifespan of Trapdoor Spiders
Trapdoor spiders can live quite a long time compared to other creepy crawlies. Most types live 5-10 years on average. Some species, like the brown trapdoor spider have even reached 20 years old!
Female spiders often outlive males since the males go searching for spider girlfriend’s more often above ground. This can be dangerous! The female spiders can live for decades in the safety of their burrows if they avoid predators.
For spending their lives underground, trapdoor spiders sure stick around for a long time! Their cool burrows help them stay fed and protected for a nice long life.
