Occurrence data provide an important baseline for the planning of conservation strategies and for the protection of species and habitats. However, collecting such data usually requires energy and it is time-consuming. Recently, citizen science has been shown to be a suitable approach for the study and monitoring of biodiversity, as it allows for the collection of a large number of records, distributed spatially and over time. Additionally, this approach enable the generation of new knowledge and fosters environmental awareness in the participating volunteers.
The present paper describes the data collected during the first citizenscience project on protected insect species in Italy. The dataset contains occurrence records of 31 taxa observed all over Italian national territory in 10 years for a total of 5,975 records. The aim of the project was to increase the knowledge, to document the distribution of the target taxa and to provide valuable data useful for the reporting of these insects as required by Articles 11 and 17 of the Habitats Directive.

In a changing world, exacerbated by the climate crises, environmental degradation and biodiversity loss (
Since the late twentieth century, an engaging and promising tool for collecting a large number of species records is represented by the citizen science (CS) approach. This consists in involving volunteers from the general public in scientific processes under the coordination of experts (
An important issue concerning CS projects is the reliability of the recorded data, commonly ensured by a data quality assessment process by expert scientists (
This paper presents and describes the dataset from a citizen initiative called MIPP/InNat, developed in the framework of two projects (LIFE MIPP "Monitoring of Insects with Public Participation" and InNat "Promozione della Rete Natura 2000 e il Monitoraggio a scala nazionale di specie di insetti protetti"), which is accessible through GBIF (Global Biodiversity Information Facility). The paper also provides some descriptive statistics. The CS-based data collection, which started in 2014 and ended in 2024, was supported by funding from different international and national sources and focused on the collection of occurrence data of selected and protected insect taxa.
The purpose of this publication is to share and make freely available occurrence data on protected insect species (i.e. listed in Annexes II and IV of the Habitats Directive) recorded in Italy and collected during the above-mentioned 10-year CS initiative. We describe the dataset consisting of occurrence data of 31 selected species belonging to four insect orders: Coleoptera (6 taxa), Lepidoptera (16 taxa), Odonata (7 taxa) and Orthoptera (2 taxa).
These records contribute to further the knowledge on the distribution of the target insects, thus providing an additional tool for planning specific conservation actions (
MIPP/InNat initiative.
Data were collected in all of Italy.
The MIPP/InNat initiative engaged volunteers in collecting occurrence data of protected insects.
The MIPP/InNat initiative was funded under different projects:
Volunteers were asked to use the project websites of the two projects or a specific app for Android and iOS (called MIPP and then InNat, discontinued) to upload pictures of observed target insects. The volunteers were free as to where or when to perform the observations. The following information was required during the uploading process: 1) tentative identification (species or genus level); 2) date and hour of the sighting; 3) geografic coordinates (WGS84, decimal); 4) location; 5) additional notes. The geographic coordinates were collected using the GPS sensor of the smartphone, manually by using Google Maps (which was accessible through the platforms) or by entering coordinates by hand. These precise coordinates were thus stored in the InNat database and were downloadable upon request during the project. Finally, the volunteers provided their e-mail addresses and a nicknames (no sensitive data were collected), in order to receive any feedback about their record.
In order to aid the volunteers in recognising and finding the various insects, fact sheets were provided, which included information on the morphology and ecology of the target insects.
The platform was developed using MySQL and was accessible with credentials by the project staff. Once a record was uploaded, it entered the project database with the initial status "pending". Subsequently, the experts validated the associated images and the information provided. If the record was "confirmed", it became visible on the project website to everyone. When no images were provided, the volunteers were contacted by the project team and were asked to provide further details on the record. Data without images were classified as valid only after careful consideration. This strict approach resulted in only approximately 3% of records without images being confirmed. Only validated and confirmed records were analysed and published as a dataset in the GBIF repository and are here described. Moreover, even if the volunteers had not been asked to provide the number of observed individuals during data submission, in the present dataset, an additional column about the number of the individuals observed for each record is presented and this was obtained by the project staff by counting the number of specimens portrayed in each image recorded.
The dataset contains records from all the Italian territory (Fig.

At the beginning, LIFE MIPP covered nine target species. Subsequently, during the projects InNat and START2000, additional taxa were included, reaching gradually a total of 31 protected species listed in the Annexes II and IV of the Habitats Directive, belonging to Coleoptera, Lepidoptera, Odonata and Orthoptera (Table
List of the 31 insect taxa targeted by the MIPP/InNat initiative and included in the dataset with information about taxonomic position (genus/species, order and family) and protection status (Annex HD: Annex of the Habitats Directive in which the species is listed). Taxa originally included in the MIPP project are in bold.
Remarks: Osmoderma eremita comprises the two subspecies O. eremita eremita (Scopoli, 1763) and O. eremita italicum Sparacio, 2000, as the taxonomic position of these two taxa is still under debate (
The species Euphydryas aurina (Rottemburg, 1775) is treated as a single taxon, in accordance with the the recent checklist of the European Butterflies (

Although the data collection carried out by the MIPP/InNat initiative started in 2014, the dataset contains records from 1973 to 2024 (Fig.

The dataset “Occurrences of protected species of insects in Italy” was published on the repository Global Biodiversity Information Facility – GBIF under the Creative Commons Attribution-Non-Commercial 4.0 International Licence (CC BY-NC 4.0) as an open access file (
The file consists of occurrence data for 31 species protected under the Habitats Directive (92/43/ECC). Fields in the dataset follow the Darwin Core standard (Darwin Core Maintenance Group 2021,
The dataset contains 5,968 occurrence records for a total of 6,292 specimens (numbers of individuals were counted, based on the images sent by the volunteers) (Fig.
Approximately 97% of the records are associated with an image portraying the reported insect.
Data were collected by a total of 1,180 volunteers between 2014 and 2024 during different citizen-science projects, but, as specified in the "Temporal Coverage" section, some of the reported observations were collected before the start of the project (Fig.
The pattern of the records collected during a year mainly reflects the months when adults of the 31 target species are usually most active, with the bulk of records having been collected in mid-July. This may be due to the fact that the majority of records are on Lucanus cervus (Fig.
