Introduction
Joan Díaz-Calafat is doing his PhD on Forest Ecology in the Southern Swedish Research Center at the Sveriges lantbruksuniversitet (SLU). His research topic focuses on how climate interacts with forest composition and affects understory plants and their associated pollinator communities. Joan is also doing some independent research work on Hymenoptera diversity and biogeography in the Balearic Islands.

Article
Photographic identification methods are of highly importance when it comes to reduce the animal's stress, pain and possible injuries during or after marking techniques and thus to increase the reliability of demographic parameter estimates. There is plenty of software available for photo-identification, allowing individual identification in capture...

The Black and Yellow Mud Dauber wasp (Sceliphron caementarium (Drury 1773)) is reported for the first time from two distant locations of the island of Mallorca (Balearic Islands, Spain). Possible entry pathways of this potentially invasive species to the archipelago are discussed, as well as potential threats to local biodiversity and ecologically...

Megachile sculpturalis Smith 1853 is found for the first time on the island of Mallorca (Balearic Islands, Spain). This is the first time that this exotic bee is reported from an island and is the southernmost record in Europe so far. Specimens were found in five distant locations throughout the island, which points out the current broad distributi...

Noctuidae belong to one of the largest families of night-flying Lepidoptera. However, despite being among the most common nocturnal flower-visitors, they have seldom been included in pollination networks. Similarly, the current knowledge on food plants used by adults is rather scarce. In this article, we build the first moth–plant pollen transfer n...

Complex biotic networks of invaders and their new environments pose immense challenges for researchers aiming to predict current and future occupancy of introduced species. This might be especially true for invasive bees, as they enter novel trophic interactions. Little attention has been paid to solitary, invasive wild bees, despite their increasi...

The Nearctic Sceliphron caementarium (Drury, 1773) is widely distributed in the Western Palearctic and is spreading to new territories. Despite the large quantities of data on citizen-science platforms, these records have been mostly overlooked. In this publication, the first records of S. caementarium from six Eastern European and Balkan countries...

Es notifica per primera vegada la presència del gènere Cephalonomia Westwood 1833 a Balears. Es tracta de petites vespes paràsites de larves de coleòpter que poden comportar un risc potencial per a la salut humana. Les picades d’aquestes vespes són doloroses i poden produir reaccions al·lèrgiques severes a algunes persones. Es presenta també un lli...

Es detecta per primer cop Camponotus barbaricus Emery 1905 a dues localitats a l’illa de Mallorca. Fins ara desconeguda, aquesta espècie de formiga passa a ser la més grossa de tota la nostra fauna. Seria estrany que una formiga d’aquestes dimensions i de comportament agressiu cap a altres artròpodes s’hagi passat per alt fins ara. Per això, sembla...

Opportunistic exploitation of a male Rhodanthidium sticticum (Fabricius, 1787) regur-gitated nectar as food resource by a worker of Plagiolepis pygmaea (Latreille, 1798) is reported. To the author’s knowledge, this is the first time that an exploitation of such resource is described. It is discussed whether this is just a random event or part of th...
Conference Paper
As a response to concerns for the conservation of pollinator diversity, mitigation measures are being initiated in the Netherlands by a wide variety of organizations and private individuals. Most of these efforts focus on the restoration of floral resources, by sowing wildflower mixtures and/or improving terrain management. Such initiatives are, ho...

"Is Sphodromantis viridis (Insecta: Mantidae) invading the Balearic Islands?" Over the years, the Balearic Islands have been suffering the arrival of a large number of exotic species, both fauna and flora. With regard to fauna, different species of vertebrates and invertebrates have reached the archipelago, causing a negative impact on resources a...

The order Hymenoptera is considered a very diverse biological group that concerns a great quantity of species commonly referred as bees, wasps and ants. However, not all the members of this insect order belong to the categories above. This group provides us with a great variety of ecosystem services (pest control, pollination, seed dispersal…), bec...

A first record for Plagionotus arcuatus (Linnaeus, 1758) in the Balearic Islands is documented through firewood pathway. This pathway is novel for the Balearic Islands, consequently biosecurity protocols at the archipelago should be activated in order to prevent the arrival of new alien species that could affect insular biodiversity.

Project
The aim of this project is to broaden the knowledge regarding Hymenoptera biodiversity, biogeography, corology and phenology in the Balearic Islands. The focus is mainly on Aculeata Hymenoptera, even though the occasional attention to Terebrantia is also paid. Currently, this project does not receive any funding.
