Araneus alsine: The Intriguing World of the Strawberry Spider


Araneus alsine, commonly known as the Strawberry Spider, is a fascinating and colorful species of orb-weaving spider belonging to the family Araneidae. Found mainly in Europe, these distinctive spiders are named for their vibrant red or orange coloration, which closely resembles the fruit they are named after. In this article, we will delve into the captivating world of the Strawberry Spider, exploring their morphology, distribution, habitat, behavior, reproduction, and conservation status.


Araneus alsine is a medium-sized spider, with females typically measuring 7-15 mm and males 5-9 mm in body length. Their most striking feature is their vibrant coloration, which ranges from bright red to orange, sometimes with a pattern of white spots on the abdomen. This colorful appearance provides the spider with effective camouflage among the flowers and foliage of their preferred habitat. The legs are adorned with black bands and are covered in spines, which aid in prey capture and handling. Like other orb-weavers, Araneus alsine has two main body segments: the cephalothorax (fused head and thorax) and the abdomen.

Distribution and Habitat

The Strawberry Spider is found across Europe, from the Iberian Peninsula in the west to the Urals in the east, and from Scandinavia in the north to the Mediterranean region in the south. They are particularly prevalent in countries such as France, Germany, the United Kingdom, and Poland.

Araneus alsine prefers habitats with tall grasses, bushes, and trees, such as meadows, forests, and forest edges. They are most commonly encountered in the herbaceous layer of vegetation, where they build their orb webs among flowers and leaves. This choice of habitat not only provides them with effective camouflage but also ample prey opportunities.

Behavior and Diet

Like other orb-weaving spiders, the Strawberry Spider is a passive hunter, constructing intricate orb-shaped webs to ensnare its prey. Their webs consist of a series of concentric circles connected by radial threads and are typically built close to the ground or in low vegetation.

Araneus alsine feeds primarily on flying insects, such as flies, mosquitoes, and moths, which become entangled in the sticky threads of their webs. Once the prey is captured, the spider quickly immobilizes it with venom and wraps it in silk, storing it for later consumption. The Strawberry Spider is diurnal, meaning it is active during the day and rests at night.


Araneus alsine follows a seasonal reproductive cycle, with mating occurring in the summer months. During this time, male spiders seek out females by following the pheromone trails they leave on their webs. Mating is a risky endeavor for male spiders, as females are often larger and more aggressive, occasionally cannibalizing their mates after copulation.

After mating, the female constructs a silk egg sac, in which she deposits her eggs. The egg sac is typically hidden among vegetation or attached to the web, providing the developing spiderlings with protection from predators. Once hatched, the young spiders disperse by a process called ballooning, where they release a silk thread that catches the wind and carries them to new locations.

Conservation Status

The Strawberry Spider is not currently considered to be a threatened species, and its population appears to be stable. However, as with many other invertebrates, it faces potential threats from habitat loss, pesticide use, and climate change. To ensure the continued survival of this colorful and fascinating species, conservation efforts should focus on preserving and protecting their preferred habitats and monitoring populations to detect potential declines.


The Strawberry Spider, Araneus alsine, is a fascinating and vibrant member of the orb-weaver family, captivating both professional and amateur naturalists alike with its colorful appearance and intricate web-building abilities. Its distribution across Europe and preference for habitats rich in vegetation make it a vital component of many ecosystems, where it contributes to the control of insect populations.

Understanding the biology, behavior, and ecological role of the Strawberry Spider not only adds to our general knowledge of spider diversity but also underscores the importance of conserving the diverse array of habitats that support these remarkable creatures. As we continue to learn more about Araneus alsine and other invertebrates, we are reminded of the intricate interconnectedness of our natural world and the need to preserve and protect the many species that contribute to its delicate balance.
