This black invertebrates_freshwater has bright orange swellings on the upper parts of the legs. The taxonomic status of this weevil is not clear; it is thought that it may be the same species as P. assimile, which is common. Further work is therefore needed to determine if this is the case (1).
This weevil is listed as a priority species under the UK Biodiversity Action Plan and a Species Action Plan has been produced to coordinate its conservation. The most pressing requirement is for the taxonomy of this weevil to be determined (1). If it does prove to be an endemic species, conservation action can begin. In the mean-time, however, monitoring is in place to keep track of the populations.
The UK Biodiversity Action Plan for this species is available at UK BAP.
A species or taxonomic group that is only found in one particular country or geographic area.
A winter survival strategy characteristic of some mammals in which an animal’s metabolic rate slows down and a state of deep sleep is attained. Whilst hibernating, animals survive on stored reserves of fat that they have accumulated in summer. In insects, the correct term for hibernation is ‘diapause’, a temporary pause in development and growth. Any stage of the lifecycle (eggs, larvae, pupae or adults) may enter diapause, which is typically associated with winter.
Stage in an animal's lifecycle after it hatches from the egg. Larvae are typically very different in appearance to adults; they are able to feed and move around but usually are unable to reproduce.
A type of coastal grassland found only in western Ireland and the north and west of Scotland that is characterised by calcareous sand blown inland by strong winds.
