  abstract = {{B}ackground {B}iological invasions pose risks to the normal functioning of ecosystems by altering the structure and composition of several communities. {M}olluscs stand out as an extensively studied group given their long history of introduction by either natural or anthropogenic dispersal events. {A}n alien population of the lymnaeid species {O}rientogalba viridis was first sighted in 2009 in southern {S}pain. {I}n its native range ({A}ustralasian), this species is one of the main intermediate hosts of {F}asciola hepatica, a major worldwide trematode parasite largely affecting humans, domestic animals and wildlife. {M}ethods {W}e collected field populations of {O}. viridis from its native ({M}alaysia) and invaded ({S}pain) ranges. {W}e performed detailed morphoanatomical drawings of the species and screened for natural infection of parasites. {I}ndividuals were molecularly characterized using {ITS}2 for comparison with existing sequences in a fine phylogeography study. {W}e founded experimental populations at two different conditions (tropical, 26 degrees {C} and temperate, 21 degrees {C}) to study the life-history traits of exposed and non-exposed individuals to different {F}. hepatica isolates. {R}esults {W}e found a 9% natural prevalence of trematode infection (98% similarity with a sequence of {H}ypoderaeum conoideum [{E}chinostomatidae]) in the {S}panish field population. {T}he haplotypes of {O}. viridis found in our study from {S}pain clustered with {A}ustralian haplotypes. {E}xperimental infection with {F}. hepatica was successful in both experimental conditions but higher in tropical (87% prevalence) than in temperate (73%). {O}verall lifespan, however, was higher in temperate conditions (mean 32.5 +/- 7.4 weeks versus 23.3 +/- 6.5) and survivorship remained above 70% during the first 20 weeks. {I}n parasite-exposed populations, life expectancy dropped from an overall 37.75 weeks to 11.35 weeks but still doubled the time for initial cercariae shedding. {C}ercariae shedding started at day 23 post-exposure and peaked between days 53 and 67 with an average of 106 metacercariae per snail. {C}onclusions {W}hether {O}. viridis will succeed in {E}urope is unknown, but the odds are for a scenario in which a major snail host of {F}. hepatica occupy all available habitats of potential transmission foci, ravelling the epidemiology of fasciolosis. {T}his research provides a comprehensive understanding of {O}. viridis biology, interactions with parasites and potential implications for disease transmission dynamics, offering valuable insights for further research and surveillance.},
