TL;DR: A large colony of Euscorpius flavicaudis was studied at Sheerness Docks, Isle of Sheppey, Kent and, in general, this species does not behave in any way that can be correlated with living in a temperate rather than a desert area.
Abstract: A large colony of Euscorpius flavicaudis was studied at Sheerness Docks, Isle of Sheppey, Kent. It was probably established in the late nineteenth century. The scorpions inhabit cracks in the dockyard perimeter wall where the mortar pointing has crumbled away. They are nocturnal, “sit-and-wait”, generalist predators. They are extremely sedentary: females leave their cracks fewer than 10 times per year; males are more active as they become vagrant prior to the mating season, which occurs in summer. Marked adults were resighted at intervals of over a year and the distance scorpions moved between resightings was not proportional to the interval. The number of scorpions seen per night was influenced by temperature, amount of rainfall and phase of the moon. In winter, the scorpions retreated far into the wall and, by doing so, reduced the risk of suffering mortality due to cold. During this time, they were seldom active. In general, this species does not behave in any way that can be correlated with living in a temperate rather than a desert area. This illustrates the extreme adaptability of scorpions.

TL;DR: Evidence strongly suggests that there are two instars of adults of the Euscorpius flavi- caudis: some males and females mature at the sixth instar and some at the seventh.
Abstract: The life-history of an English population of the scorpion, Euscorpius flavi- caudis,was studied using morphometric measures of over 300 specimens . The study hy - pothesizes seven instars . Evidence strongly suggests that there are two instars of adults : some males and females mature at the sixth instar and some at the seventh . Larger scorpion s may have a higher per-season reproductive success but may have fewer reproductive season s owing to the extra time needed to mature .

TL;DR: Investigation of the functional advantage of parental care in Euscorpius flavicaudis showed that the presence, or absence, of the female had no effect on juvenile survival when conspecific scorpions were kept from the experimental scorpions, but when other scorpions had access to the experimental Scorpion, the presence of thefemale prevented predation; in her absence brood mortality averaged 99 %.
Abstract: Scorpions exhibit parental care, whereby the female carries her 1 st instar young upon her back for the duration of the instar. The one species of scorpion to be found in England, Euscorpius flavicaudis, was used to investigate the functional advantage of parental care. Laboratory conditions, modelled on the natural habitat of this scorpion, showed that the presence, or absence, of the female had no effect on juvenile survival when conspecific scorpions were kept from the experimental scorpions. However, when other scorpions had access to the experimental scorpions, the presence of the female prevented predation; in her absence brood mortality averaged 99 %. This is hypothesised to be the major selective advantage to parental care. Other advantages may occur (e.g. trophic exchange, female moderating microclimate, some form of "group effect"-increased survival of larger groups of juveniles) but these are secondary in relation to the avoidance of prcdation.

TL;DR: Although hemispermatophores are complex, they are not more informative than other morphological characters and may be useful for species discrimination, but in closely related species they are of limited taxonomic value.

TL;DR: A review of the scorpions found in the urban habitat of Rome, Central Italy, together with an analysis of the factors which affect their distribution and abundance in the town, is pointed out as mentioned in this paper.
Abstract: A review of the scorpions (three species of the genus Euscorpius, family Chactidae) found in the urban habitat of Rome, Central Italy, together with an analysis of the factors which affect their distribution and abundance in the town, is pointed out. It appears that Euscorpius carpathicus, a species commonly found on limestone terrains in Latium, is frequent, though not particularly abundant, in the urban area of the city especially along the course of the Tiber River. It appears that Euscorpius flavicaudis, a species commonly found on volcanic terrains in Latium and the most common terrains in and around the area of Rome, is the most common species in both the urban and suburban areas of the city. It appears that Euscorpius italicus, a species common in north and northeastern Latium, is represented, in the sample of the scorpions of the city, by a single, possibly aberrant, specimen.
