This program subsidizes the cost of mobility through the provision of a grant that includes travel costs, accommodation, insurance and linguistic and cultural preparation. Being a citizen of the European Union and with a degree in Biology. I had the opportunity to do an internship in an organization in another country and Italia was the country chosen. The internship was held in the Museo di Storia Naturale di Firenze – La Specola, entomological department and had a duration of 21 weeks. 1.2 Natural History Museum of Florence The Museum of Natural History in the University of Florence consists of six departments distributed in palaces and monumental places in the center of Florence. In these institution, we can find with an extraordinary scientific and naturalistic value: the centuries herbaria, the precious seven hundred wax models, the fossil skeletons of large mammals, collections of multicolored butterflies, large crystals of tourmaline, the spectacular maori masks, ethnic jewellery of native peoples, the monumental trees of the Botanical Garden, etc. An environment which combines nature, history, science and art. The Museum offers to visitors - alone or with your family - paths, guided tours and workshops for all ages. Founded in 1775 by the Grand Duke Peter Leopold of Habsburg-Lorraine, with the name "Imperial Royal Museum of Physics and Natural History," was one of the first science museums in the world. On that occasion, the natural history collections and scientific instruments, stored in the Uffizi Gallery, were reunited in the Via Romana. Among the new features offered by the Museum of the proceedings commenced Torrino, hence the name "The Observatory", which proposes a new path and an exhibition that hosts the best of historical and scientific collections. The section of Mineralogy and Lithology offers a new version that allows the visitor to discover the extraordinary collections of Elba and Brazilian toumalines, the 2 beautiful samples from Sicily and Sardinia and art objects in precious stones of the Medici Collections. Visiting the Museum of Natural History is an extraordinary experience. 1.2.1 La Specola The Museum the Observatory, founded by Grand Duke Peter Leopold of Lorraine, was opened to the public in 1775 and is the oldest science museum in Europe. It contains the largest collection in the world of anatomical waxes, made between 1770 and 1850, and over 3,500,000 animals, of which about 5,000 exposed to the public. Currently The Observatory is a section of the Museum of Natural History. 1.2.1.1 Entomological department In the entomological collections of the Museum there are about a million specimens, including groups of arthropods that are not insects, such as spiders, scorpions, centipedes, etc.. It is an enormous amount of scientific samples from diverse backgrounds, the oldest of which date back to the first half of XIX century. Unfortunately, the samples of the first entomological museum collections eighteenth century the most important ones are not preserved. The core of the collection consists of material of two origins: there are insects collected by researchers at the Museum during travel, study, and exploration missions, and then there are the collections but made by individuals, arrived at the Museum by donations or purchases, usually after the death of the collector. Among the historical collections, one of the most important is the collection of Diptera and Hymenoptera assembled by Camillo Rondani. Rondani was a distinguished entomologist and described a large number of new species, and its collection therefore has a huge scientific value, since it includes Types of whom he appointed the new species; scholars and experts from all over the world have therefore constantly need to examine this material to solve various taxonomic and systematic problems. Another collection of great importance is the Roger Verity collection, even in this collection there are about two thousand specimens on which Verity described new species, breeds or varieties. The Observatory has preserved one of the most important collections in the world of beetles of the family of Brentidi. These curious elongated 3 insects live for the most part in tropical forests around the world, and the presence of such a rich collection to the museum is due to the fact that some of the most important specialists worldwide have worked on these beetles, in Florence The first was Professor Angelo Senna, who described many new species and published a large number of publications, he was later joined by his pupil Enrica Calabresi. In recent times, some private collections ended up in the collections of the Museum, significantly increasing the number of specimens and their scientific value. If you can refer three in particular: the collection Andreini, the collection Failla and the collection Rocchi. 2 Main Activities Developed 2.1 Placement of insects in the collection department After being identified the gender and species of each insect it is placed in their respective family. My first activity was to grab insects already identified and insert them in the Museum collection. This job allowed me to understand the operation of storage of insects. The insects are stored in cupboards, (figure 1), each cupboard can be composed by one or more families, depending on the size of it. All cupboards are properly identified outside, with the initials of each family by alphabetically order. Each cupboard is composed of numbered boxes, where insects are preserved (figure 2, 3). Each family has a checklist, the same is organized by genus, respective species and box number. For placement of insects the first thing to know is the family, then get on their checklist and see the box number for the genus. Figure 1 - Organizing the closets where they keep the insects 4 Figure 2 - The cabinets are constituted by boxes, where insects are preserved. There are species that are not identified; these species are placed in the family to which they belong, in boxes referent to the region where they were collected. 2.2 Separation of Arthropods by order Arthropods are a phylum of invertebrate animals that have hard exoskeleton and several pairs of jointed appendages, whose number varies according to the class. They are the largest phylum of animals, represented by animals such as locusts (insects), spiders (arachnids), crabs (crustaceans), and centipedes (chilopods). The adult arthropods with soft body and the young insects are preserved in alcohol 70%. If the intention is that they remain preserved for long (for years), the smaller glass must be placed within a largeri glass also containing alcohol 70%, because evaporation is a constant risk. Thus the evaporation occurs only in the large glass, facilitating the replacement of the alcohol. The first step to identify what is collected in the field, is separated the animals by orders. This activity consisted in taking these bottles with arthropods in alcohol, and with the help of the microscope, separating them by Orders. Each order is placed in vials with 5 alcohol and is stored by region / country with a label written in pencil, they are thus kept until identified in families, genus and species. 2.3 Reorganization of entomological collections Three entomological families were reorganized: Chrisomelidae, Buprestidae and Coccinelidae. The reorganization of the families is very important, since the families are increasing, therefore, boxes where insects are inserted don't have space and the same species are in different boxes. This activity was intended to make a new checklist for the three families, and structure the families again, so that the same species stay in the same box or else in the next box and not at the end of the family. The checklist were made in excel, them are mentioned genus and its author, species and its author and box number. Figure 3 - Chrysomelidae family reorganization 6 2.4 Learning collection methods in the field Were made three visits to the field, in order to learn the different types of insects collecting methods. Different materials were used for the collection thereof, such as shown below shown. Field trip 1 Being the first field trip, the aim was to use different methodologies for collection and get the biggest possible species of insects. Were used: Network – used to capture insects that are resting or feeding on vegetation. It is very similar to the network, but is made with resistant cotton fabric to ensure its durability, since when contacting with the vegetation it can grab the branches, thorns and leaves. Tweezers and brushes – prevent the catcher gets hurt and that the frail body of the insect to break. The tweezers can be thin or rounded, the most common are those used by doctors and dentists Entomological sucker – this instrument is used to remove small insects from the entomological net or suck them directly from vegetation. It has the advantage of selecting the insects that are of interest before capture. Bottle lethal - glass bottle containing ether. Ideal to kill adult insects in general: flies, dragonflies, beetles, bugs, ants, grasshoppers, crickets, bees, wasps. Paper envelopes– as the Lepidoptera should not be killed in deadly jar, ideally transport them alive in triangular paper envelopes until they can be killed properly. Its preparation is simple and must stay within the envelope with their tips bent. 7 Figure 4 - Explanation of the method to collect butterflies Figure 5 - Field work team. 8 Field trip 2 This trip consisted of the catching of butterflies and dragonflies, the material used is only a network, used to catch insects in flight. It is made of thin transparent tissue, which allow us to see the captured insect, as Figure 5 and 6 demonstrates. Once captured they are placed in envelopes until being identified. Figure 6 - Butterflies catching Figure 7 - Network Scanning used to capture 9 Field trip 3 The main objective of this field trip was to learn how to capture aquatic insects. The insects were captured on the banks of the water bed, with nets and stored in bottles or jars with alcohol. Figure 8 - Monitoring of water beetles Figure 9 - Captured Lucanus cervus 10 2.5 Learning how to prepare and classify insects MOUNTING After the insects are dead, the ideal is that they are mounted as fast as possible. If insects have already hardened, they will become brittle and difficult to handle. Thus, they must remain in a moist chamber until they can be pinned and its appendages positioned correctly. The copies of the collection should be pinned with only entomological pin, which are made of steel and will not rust. The position of the pin is generally inserted vertically between the first and second pair of legs, so that it is at an angle of 90 ° relative to the longitudinal axis of the body of the insect. Each group of insects has a specific position. Figure 10 - Preparation of insects, for later identification LABELING All insects in a collection, stored dry or humid, should contain labels white, written in pencil or printed. The insects of a museum have two labels: one of origin, other of identification. 11 The first label to be raised as to origin, which must contain: • City, state, country. • Date with month in Roman numerals. • Collector ‘ name, followed by the abreviated name The second label of identification must contain the information that we have on the specimen collected, i.e he name of the order, family, genus or species. In insects pinned, labels must be placed so that they are parallel to the body of insects at a uniform height on the pin. To this can be used a block of wood to standardize the height. They should be oriented so that information contained therein can be read all the same side. Figure 11 - After identified, the insects are put in boxes 12 3 Final Considerations The objectives that was been proposed at professional level were achieved, because I had the opportunity to participate and organize various activities. I had the opportunity to apply some of the knowledge I had acquired earlier during the degree, however, what I consider most important is the fact that I have increase my knowledge. It was a very rewarding and challenging experience, both at the professional level as personal. It was definitely an experience very important in my life. At personal level, had the opportunity to attend a course of Italian linguistic, which was very important. I had the opportunity to visit all sections of the Museo of the institution in Florence. My advice is that all people can live such an experience, enjoy, because when we live, work or study in another country we really see life in a different way. 13 4 Bibliographical References http://ec.europa.eu/education/lifelong-learning-programme/ldv_en.htm (Accessed in 23/08/2013) http://paginas.fe.up.pt/~sicc/dcoop/re/ProgramaLeonardodaVinci.htm (Accessed in 23/08/2013) http://www.msn.unifi.it/CMpro-v-p-1357.html (Accessed in 23/08/2013) http://ocondedemontecristo.files.wordpress.com/2013/07/coleta-montagem-econservac3a7c3a3o-de-insetos.pdf (Accessed in 23/08/2013) 14
