The insects of the Tassaro valley


Val Tassaro is populated by a large number of insects, belonging to numerous species. The particular environmental conditions lead us to believe that this population is high.

Alongside species that live and draw nourishment from the wood of trees, there are others specialized in living in rocky ravines or within the clear waters of the stream. Particularly significant is the presence of butterflies, the number of which is an indication of the ecological quality of the area.

Some species are exclusive to certain periods of the year, such as fireflies, which in May are widespread along the hedges at the edge of the woods. Also very indicative is the spread of the field cricket, whose high-pitched trills spread in spring in meadow clearings.


The spiders of the Reggio Emilia Apennines play a crucial role in local ecosystems, contributing to the control of insect populations and maintaining the ecological balance. The diversity of habitats, ranging from forests to alpine meadows, offers unique opportunities for the adaptation and specialization of spider species present in this region.

These arachnids display an extraordinary variety of behaviors, hunting abilities and morphological adaptations. Studying the spiders of the Reggio Emilia Apennines not only provides a fascinating overview of local biodiversity, but also contributes to a broader understanding of the biology and ecology of these fascinating predators.


The butterflies of the Reggio Emilia Apennines are a symbol of delicacy and beauty, dancing among colorful flowers and across alpine meadows. These vibrant and nuanced wings, a symbol of transformation and fragility, play a crucial role in the local ecosystem, contributing to the pollination of plants and acting as a sensitive indicator of environmental conditions.


The beetles of the Reggio Emilia Apennines present a notable diversity in terms of shape, size and behaviour. From the flashing lights of fireflies to the vibrant colors of flower beetles, the region offers a fascinating insight into the biological richness of these insects. Adaptation to specific habitats and the unique behaviors of each species help create a complex picture of beetle life in this mountainous region.

Bees, bumblebees, wasps

The Reggio Emilia Apennines are home to a varied community of pollinating insects, including bees, bumblebees and wasps, essential for the health of local ecosystems and for food production. These insects play a crucial role in the reproduction of flowering plants, contributing to the formation of fruits and seeds.

Bees, with their social organization and pollination process, are among the best-known and most important insects. Bumblebees and wasps, which are also involved in pollination, have unique behaviors and characteristics that set them apart. The species diversity in this mountainous region offers a rich and complex insight into the world of pollinating insects.


Flies, belonging to the Diptera order, are a very diverse group of insects that are also found in the Reggio Emilia Apennines. This region offers a wide range of habitats, from woodlands to grasslands, providing the ideal environment for the presence of different species of flies.

Flies present a remarkable variety in terms of morphology, behavior and life cycle. Some species specialize in the decomposition of organic matter, contributing to the decomposition process and the recycling of nutrients. Others play key roles as pollinators or are involved in complex ecological interactions with other organisms.

The importance of flies goes beyond their reputation as annoying insects. They are fundamental in the balance of ecosystems, participating in essential nutrient cycles and contributing to the control of other insect populations.


Scorpions play an important role in ecosystems, helping to control populations of insects and other small organisms. They are nocturnal predators that feed on various insects, spiders and small invertebrates.


In the Reggio Emilia Apennines, scorpions can find refuge in rocky crevasses, under tree trunks or in other natural crevices. Their presence may be indicative of rich biological diversity, as the presence of predators such as scorpions can help maintain balance within ecosystems.

It is important to note that although some scorpions can be venomous, most species do not pose a significant threat to humans. Scorpions are fascinating beings from a biological point of view, and the study of their presence in the Reggio Emilia Apennines contributes to a broader understanding of the fauna of this mountainous region.

Praying mantis

The praying mantis, with its slender body and specialized front legs, plays an important role in the ecosystem of the Reggio Emilia Apennines. This voracious predator feeds mainly on insects, contributing to the natural control of populations of flies, moths and other small invertebrates.

Its presence adds a unique touch to the rich biodiversity of this region, with its ability to blend into the surrounding foliage. In addition to its fascinating visual appearance, the praying mantis is involved in intriguing reproductive behaviors, such as the well-known cannibalism during mating, which adds an element of curiosity to its biology.
