Metellina merianae is a spider species found in Europe up to Georgia. They most commonly dwell in the entrances of caves but can also be found in burrows and hollow trees. Web structure is specific to each species. The webs of M. merianae reach up to about 100 squared cm.

Adorned with a mottled pattern that camouflages it amidst foliage and bark, eurasian armoured long-jawed spider weaves orb-shaped webs. With the arrival of autumn, it's not uncommon to witness a frenzy of mating and egg-laying, ensuring its lineage persists through their offspring, who emerge in the following spring. Their diet fluctuates from small insects during youth to larger prey as they mature, displaying their adaptability in various European habitats.

Metellina. mengei is very similar to Metellina segmentata, from which it can only be discerned by comparing genital features. It is about 5 mm long. Adults are found from May to July.

Tetragnatha viridis is a species of long-jawed orb weaver in the family of spiders known as Tetragnathidae. It is found in the United States.

Expertly camouflaged among vegetation, tetragnatha hasselti boasts elongated chelicerae and a body that can appear almost stick-like when at rest. Preferring habitats near water, it displays remarkable adaptability, with a diet that shifts from aquatic prey during its juvenile stage to flying insects in adulthood. This shift showcases a fascinating developmental transformation aligning with environmental opportunities for sustenance.

Residing primarily in wetland habitats, green big-jawed spider is known for its distinctive elongated body and jaw structure, adaptations that render it an adept ambush predator. With a diet primarily consisting of insects, this species displays marked sexual dimorphism, with females frequently out-sizing the males. It intricately weaves orb-shaped webs, often close to water sources, to capture prey, showcasing a remarkable nocturnal activity pattern and exhibiting a significant role in local ecosystems as a natural pest controller.

The common stretch spider folds its body into a straight line, often on a plant stem or leaf vein, to camouflage itself when acting defensive. It can also run on water faster than it can move on land. The egg sacs, laid on leaves, are covered in gray silk and look a bit like bird droppings.

With elongated bodies and limbs, tetragnatha obtusa exhibit remarkable agility in their arboreal habitats. They possess the unique ability to stretch out stick-straight among twigs, which, coupled with their adaptive coloring, renders them practically invisible to predators and prey. Their diet encompasses a variety of insects, ensnared in intricate, orb-shaped webs that glisten with morning dew, showcasing their exceptional engineering skills. As night falls, these arachnids are active hunters, using their keen vibration sensitivity to detect the slightest of movements from their silken traps.
