“…It invades cultivated and barren areas in gardens, forests, suburbs, and cultivated areas by creating numerous individuals in favorable conditions and mostly spend more time under grass (Herbert, 2010). Additionally, in a study of Lauria cylindracea, Anion hortensis, C. barbara, Pupoides albilabris, and Xerotricha conspurcata including their distribution to Los Angeles, Orange, and Riverside counties in California, it was emphasized that C. barbara easily adapted to the metropolises and spread fast (Vendetti et al, 2018).…”

The objective of the present study is to inform the last distribution of the invasive and harmful species Cochlicella barbara (Linnaeus, 1758) in Turkey, as well as to draw attention to the possible danger of this distribution on regional vegetation, agriculture, and parasitism. C. barbara was found for the first time in southeastern of Anatolia in April 2019 in the campus area of the Dicle University in Diyarbakır, Turkey. C. barbara is admitted as a harmful organism and classified as an agricultural pest in most of the countries. Species in this genus have been intercepted in postal packages, soil, and cargo as well as can be easily transported with plants, building materials, household goods, etc. Above all, it is an intermediate host of nematode and fluke parasites of livestock. Knowing the distribution of this species will not only contribute to the registration of a new species in the list of gastropods of the region but also facilitate the control of the species across Turkey.

“…Museum specimens of flies were slide-mounted in Canada balsam after clearing in clove oil. One snail was sequenced (GenBank Accession # MN734267), using the methods of Vendetti et al (2018). Voucher flies are deposited in the collection of the Natural History Museum of Los Angeles County and a CO1 barcode sequence of one specimen is in the BOLD database as POTW001-19.…”

BackgroundPhorid flies are amongst the most biologically diverse and species-rich groups of insects. Ways of life range from parasitism, herbivory, fungivory, to scavenging. Although the lifestyles of most species are unknown, many are parasitoids, especially of social insects. Some species of ant-parasitoids are attracted to injured hosts for feeding purposes to develop eggs, as well as for oviposition, requiring each female to find two injured hosts. New informationFemales of the phorid fly Megaselia steptoeae Hartop et al. (Diptera: Phoridae) were found to be quickly attracted to crushed glass snails of the species Oxychilus draparnaudi (Beck) (Gastropoda: Oxychilidae). Most females were without mature eggs and apparently were attracted for feeding purposes only; other injured molluscs offered at the same time were not attractive. One female laid eggs in captivity and offspring were reared to the pupal stage. The lifestyle of this species is similar to that of parasitoids of injured ants, which also require separate hosts of the same species for feeding and oviposition. We conclude that injured hosts must be common in the environment to attract these host-specific scavengers. ‡ ‡

“…For example, the Los Angeles County Museum of Natural History has initiated a new mollusk-specific citizen science program called Snails and Slugs Living in Metropolitan Environments (SLIME; https://nhm.org/ community-science-nhm/slime). There have been a number of published products associated with this program (e.g., Ballard et al 2017;Vendetti et al 2018), and the vast majority of records in Los Angeles County (and by extension many in our dataset) are a product of participants of this program via iNaturalist. Thus, while these efforts have been successful and prolific, we advise caution when using all data provided for geospatial modeling without first accounting for common sources of geospatial error (e.g., spatial autocorrelation, pseudo-replication).…”

The contiguous United States (CONUS) harbor a significant non-native species diversity. However, spatiotemporal trends of some groups such as terrestrial gastropods (i.e., land snails and slugs) have not been comprehensively considered, and therefore management has been hindered. Here, our aims were to 1.) compile a dataset of all non-native terrestrial gastropod species with CONUS occurrence records, 2.) assess overarching spatiotemporal patterns associated with these records, 3.) describe the continental origin of each species, and 4.) compare climatic associations of each species in their indigenous and introduced CONUS ranges. We compiled a georeferenced dataset of 10,097 records for 22 families, 48 genera, and 69 species, with > 70% of records sourced from the citizen science database iNaturalist. The species Cornu aspersum Müller, 1774 was most prevalent with 3,672 records. The majority (> 92%) of records exhibit an indigenous Western European and Mediterranean distribution, with overlap in broad-scale climatic associations between indigenous and CONUS ranges. Records are most dense in urban metropolitan areas, with the highest proportion of records and species richness in the state of California. We show increased prevalence of non-native species through time, largely associated with urbanized areas with high human population density. Moreover, we show strong evidence for a role for analogous climates in dictating geographic fate and pervasiveness between indigenous and CONUS ranges for non-native species.
