Four new species were found during June

     


Giant House Spider  Tegenaria atreica 



The Giant House Spider is one of several similar looking species which inhabit houses and outbuildings - hence the common name house spiders.


It has earthy tones of brown and muddy red or yellow. They also have conspicuously hairy legs, palps and abdomen. Despite its English name, this species is not the largest species in the genus


The female body size can reach 18.5 millimetres (0.73 in) in length, with males having a slightly smaller body at around 12 to 15 millimetres (0.47 to 0.59 in) in length.

The female leg span is typically around 45 millimetres (1.8 in). The leg span of the male is highly variable, with spans between 25 to 75 millimetres (0.98 to 2.95 in) being common.

 

The bite of this species does not pose a threat to humans or pets, and it is generally reluctant to bite, preferring to escape.

 

 Found throughout the UK.  All year round



Purple Toadflax Linaria purpurea 


An erect perennial with stiff stems and pale green leaves, it bears tall dense flower spikes of dainty pale purple flowers, each with two lips and spurs, rather like snapdragons.

Ultimate height0.5-1 metres June to August.




Potter Wasp Ancistrocerus nigricornis   



Ancistrocerus nigricorniscan reach a length of 6–10 millimetres (0.24–0.39 in) in males, of 9–13 millimetres (0.35–0.51 in) in females.


These potter wasps live in wet meadows, in open landscapes, sometimes in gardens and in areas where their feeding and preferred nesting sites are present


Adults emerge in late summer. Males can be seen from June until September, while females have been recorded from February to October.


After mating the males die and the females overwinter and reappear in the spring
