“…In accordance with Massa [18], the presence at Pantelleria of phytophagous species strictly linked to allochthonous plants, imported to the island in the last decades, is certainly the proof of a speedy immigration of insects, at least concerning small and light species driven by the winds. However, the present fauna and flora of Pantelleria are more related to their Italian than to their North African counterparts ( [17], [18], [19], [20],…”

In late April 2022, during the hearing of the audio files from an unsupervised bioacoustic assessment of the shearwater populations (Aves, Procellariiformes) on the coast of Pantelleria island (Italy, Sicily), a cricket song of unknown attribution was heard. The first bioacoustic analyses, including FFT-based spectrograms and sound pressure envelopes, confirmed that it could not be attributed to the known sound of any Italian nor Mediterranean species of cricket. In the ensuing weeks, field research made on purpose in the original station and in further localities in the southern coast of Pantelleria provided photographs, living specimens and further audio records. As soon as the photos were shared among the authors, it became clear that the species belonged to the genus Acheta. Further bioacoustic analyses and morphological comparison with type specimens of Mediterranean and North-African congenerics in relevant collections and in the scientific literature were conducted: they confirmed that the findings could only be attributed to a still undescribed species, that escaped detection due to its impervious and unfrequented habitat. Acheta pantescus n. sp. is apparently restricted to the effusive coastal cliffs of the island of Pantelleria, a habitat whose scant extension and vulnerability require environmental protection actions such as the inclusion in a special Red List by the IUCN Italian Committee.

“…This species is distributed across Portugal, the southern half of Spain and in Morocco (Eades et al, 2013in Vega & Segura, 2013. Mohamed Sahnoun et al, (2010) mentioned in his checklist 12 species belonging to this genus in different local of the Algerian territories while Vega and Segura, (2013) The Sciobia genus has been reported by several authors as a food source for some species: it was consumed by barn owl (Tyto alba (Scopoli 1769) (Aves : Strigiformes)) in Morocco (Rihane, 2005), by coot (Fulica atra (L. 1758) (Aves : Rallidae)) in Algeria (Metna, 2012) and by Algerian hedgehog (Atelerix algirus (Lerboullet 1842) (Mammalia : Erinaceidae)) in Algeria (Mimoun, 2006). In this work during the characterization of the trophic menu of Bubulcus ibis in the El Kala region, we discovered for the first time the presence of the species S.(S.) bolivari (Chopard 1937) in Algeria.…”

In order to determine the diet of the cattle egret Bubulcus ibis (L. 1758), a study was carried out from January 2017 until July 2018 in two integral wetlands in El Kala National Park (PNEK). These two sites are included in the list of the Ramsar Convention on wetlands of international importance. They are located in northeast Algeria: Oubeïra Lake (36° 50' N, 08° 23' E) and Tonga Lake (36° 53’N, 08° 31’E). The results obtained on a total of 126 cattle egrets allowed us to detect among the ingested prey found in the stomach contents, one species of Orthoptera related to the Ensifera suborder: Sciobia (Scioba) bolivari (Chopard 1937) for the first time in Algeria. This work provided the first report on Sciobia (Scioba) bolivari.

“…Members of the genus Pseudomogoplistes are highly unusual for crickets in that they occur very close to the sea, under cobbles and amongst shingle near to the upper strand line (Sutton 1999(Sutton , 2015Benton 2012;Dusoulier 2017). P. vicentae is known to occur in small and apparently isolated populations in four places in the U.K. (Branscombe, Devon, Marloes sands and Dale beaches, Pembrokeshire and Chesil Beach, Dorset), the Channel Islands (Sark and Guernsey), France (Brittany and Normandy), the Atlantic coast of Spain, Portugal, Morocco, Algeria (Habibas Islands) and the Canary Islands (Gorochov 1996;Sutton 1999Sutton , 2015Sutton et al 2017;Morère and Livory 1999;Livory et al 2000;Sahnoun et al 2010;Benton 2012;Hochkirch et al 2016a, b;Kleukers et al 2018). Where the species does occur, the populations tend to be found within very restricted areas of suitable habitat (Timmins 1994b;Sutton 1999Sutton , 2015Sutton et al 2017;Hudson 2006;Gardiner 2009).…”

The Atlantic Beach-Cricket, Pseudomogoplistes vicentae, inhabits shingle beaches, with a range that extends from the UK to the Canary Islands. Little is known about the natural history of this species, which is listed by the IUCN as Vulnerable. In the present study, a combination of field sampling (by pitfall trapping and direct searching) in spring, summer, autumn and late winter at two different sites in the UK, together with culturing eggs and nymphs in captivity, was used to determine the life cycle. Eggs laid in August in captivity showed no visible embryonic development until May and hatched the following July. There was no difference in the time taken to hatch between eggs maintained over winter at either 4 or 11 °C. Nymphal instars present in the field indicated that the majority of eggs hatch from June to early August. From October to February in the field, the majority of nymphs were estimated to be at the 7th instar. Development appeared to resume by April and nymphs reached adulthood by July to August in the field, two years after the eggs from which they hatched were likely to have been laid. The number of nymphal instars ranged from 10 to 11 (mode: 11) in males and 11 to 13 (mode: 12) in females. In captivity, most adult males died by the end of November, while 35% of females survived until March. Females preferred to oviposit in driftwood rather than in sand in the laboratory. This fact, together with the early embryonic diapause, suggests that the species might be able to disperse by rafting at the egg stage.
