Diptera belonging to the families Calliphoridae and Sarcophagidae are known for their diversified trophic preferences and for their forensic and medical-veterinary relevance. The ecological preferences (distribution, abundance and habitat) of these two families were investigated along four years in the Region Calabria (Southern Italy) in 17 sampling sites located in four areas: the Aspromonte National Park, the Sila National Park, the Natural Regional Park of Serre, and a suburban area at the University of Calabria (Rende, Cosenza, Italy). A total of 39,537 individuals were collected, with 36,253 belonging to 14 species of Calliphoridae and 3284 belonging to 35 species of Sarcophagidae. The most abundant species among Calliphoridae was Calliphora vomitoria (Linnaeus, 1758); among Sarcophagidae, it was Sarcophaga (Sarcophaga) croatica Baranov, 1941. The highest species richness and abundance of Calliphoridae were observed in forest areas and those of Sarcophagidae in open and humid environments. The results also show a close association between the distribution of both families and environmental factors such as altitude, vegetation type, season, and temperature.

Carabidae, or carabids, commonly known as “ground beetles”, are found in numerous natural and cultivated habitats and are recognized for their beneficial role in controlling phytophagous pests in various temperate agroecosystems. However, the crop type and agricultural practices used in management areas significantly affect the structure of the carabid communities. The aim of this study was to investigate the abundance and diversity of ground beetles in hazelnut agroecosystems characterized by different agricultural methods in Calabria, Southern Italy. The carabids were collected from 2017 to 2018 in three hazelnut groves referred to in this study as AZ1, AZ2 and AZ3. Carabids were sampled using pitfall traps inspected every two weeks over a period of 24 months. A total of 4665 specimens belonging to 48 taxa were collected within the sampled sites. Many taxa were found to be widely distributed across the three selected hazelnut groves. Among these, Calathus spp., Harpalus dimidiatus (P. Rossi, 1790), Nebria spp., Platyderus neapolitanus jannonei (Binaghi in Magistretti, 1955), Poecilus cupreus (Linnaeus, 1758), Pterostichus melas italicus (Dejean, 1828), and Syntomus obscuroguttatus (Duftschmid, 1812) were the most abundant ones associated with all sampled areas. Concerning trophic preference, among the collected taxa, the most abundant ones were zoophagous and zoospermophagous. Additionally, taxa uncommon in agroecosystems but with ecological relevance, such as Carabus lefebvrei lefebvrei Dejean, 1826, Carabus preslii neumeyeri Schaum, 1856, and Carabus rossii Dejean, 1826, were also collected.

Saproxylic beetles are key bioindicators of forest ecosystem quality and play essential roles in deadwood decomposition and nutrient cycling. However, their populations are increasingly threatened by habitat fragmentation, deadwood removal, and climate-driven environmental changes. For this reason, an integrated sampling method can increase the detection of species with varying ecological traits. We evaluated the effectiveness of integrative sampling methodologies to assess saproxylic beetle diversity within Sila National Park, a Mediterranean forest ecosystem of high conservation value, specifically in two beech forests and four pine forests. The sampling methods tested included Pan Traps (PaTs), Malaise Traps (MTs), Pitfall Traps (PTs), Bait Bottle Traps (BBTs), and Visual Census (VC). All specimens were identified to the species level whenever possible, using specialized dichotomous keys and preserved in the Entomological Collection TB, Unical. Various trap types captured a different number of species: the PaT collected 32 species, followed by the PT with 24, the MT with 16, the VC with 7, and the BBT with 5 species. Interestingly, biodiversity analyses conducted using PAST software version 4.17 revealed that PaTs and MTs recorded the highest biodiversity indices. The GLMM analysis, performed using SPSS software 29.0.1.0, demonstrated that various traps attracted different species with different abundances. By combining multiple trapping techniques, we documented a more comprehensive community composition compared to single-method approaches. Moreover, PaTs, MTs, and PTs recorded 20%, 40%, and 33% of the Near Threatened species, respectively. We report new records for Sila National Park, including the LC species Pteryngium crenulatum (Curculionidae) and the NT species Grynocharis oblonga (Trogossitidae). For the first time in Calabria, the LC species Triplax rufipes (Erotylidae) and the NT species Oxypleurus nodieri (Cerambycidae) and Glischrochilus quadrisignatus (Nitidulidae) were collected. Our results emphasize the importance of method diversity in capturing species with distinct ecological requirements and highlight the relevance of saproxylic beetles as indicators of forest health. These findings support the adoption of multi-method sampling protocols in forest biodiversity monitoring and management programs, especially in biodiversity-rich and structurally heterogeneous landscapes.

Landscape configuration and forest structure assume an increasing importance as determinants of animal communities. This paper focused on nocturnal Lepidoptera inhabiting alder patches in the Sila National Park, Italy. According to their shapes, patches were divided into linear and compact ones to disentangle the roles of forest structure and landscape configuration in determining the composition of nocturnal Lepidopteran communities at different observation scales. We used the Mann–Whitney test for medians and Shannon diversity, equitability, Fisher’s alpha, and nestedness to test differences among moth communities. We found that compact patches inhabited richer and more abundant communities. The abundance-based Correspondence Analysis showed moth communities clustered according to woodlot shape, except a compact woodlot with a linear-like moth community because it was entirely surrounded by grasslands. Percentage of forested area and abundance and composition of communities were positively correlated at 50 and 200 m buffers, while correlations were absent at smaller and larger buffers. Our results demonstrated that a width of 50 m may not be sufficient to give proper functionality to the wooded area, at least for moths. As a consequence, planning of forest restorations should consider the importance of increasing the structural habitat continuity at larger scales.

In the paper 89 species of Lepidoptera Tortricidae collected in the Sila Massif and surrounding territory (Calabria, southern Italy) are listed. Acleris silana sp. n. Trematerra is described and 17 species were added to the Calabrian fauna. Notes related to tortricid fauna of the region with biogeographic study and chorological analysis are also reported.

The biodiversity of wild bees (Hymenoptera: Anthophila) in southern Italy—particularly in Calabria and Basilicata—remains poorly documented despite the region’s high species richness. This study addresses this gap by assessing bee fauna through field surveys conducted across diverse habitats, including national parks, reserves, and agroecosystems, between 2016 and 2023. Bees were collected using hand nets or traps, and DNA barcoding was applied to 63 specimens to support species identification. A total of 223 species were recorded, including 10 new records for Basilicata, 57 for Calabria, 20 for southern Italy, 3 for the Italian mainland, and 1 for Italy, Eucera (Eucera) colaris Dours, 1873 (Apidae). The results reveal the unexpected presence of several central European species in mountainous areas of southern Italy, co-occurring with Mediterranean taxa. These findings indicate that these regions act as important refugia for species from both Mediterranean and Central European biogeographic zones, contributing to high regional diversity. DNA barcoding also revealed notable genetic divergence in several species compared to other European populations, highlighting the uniqueness of southern Italian bee fauna. Continuous monitoring and habitat protection are urgently needed in light of agricultural intensification and climate change.
