Giant House Spider
The giant house spider has been treated as either one species, under the name ''Eratigena atrica'', or as three species, ''E. atrica'', '' E. duellica'' and '' E. saeva''. , the three species view was accepted by the World Spider Catalog. They are among the largest spiders of Central and Northern Europe. They were previously placed in the genus ''Tegenaria''.

Hobo Spider
The hobo spider (''Eratigena agrestis'', formerly ''Tegenaria agrestis'') is a member of the family of spiders known colloquially as funnel web spiders, but not to be confused with the Australian funnel-web spider. Individuals construct a funnel-shaped structure of silk sheeting and lie in wait at the small end of the funnel for prey insects to blunder onto their webs. Hobo spiders sometimes build their webs in or around human habitations. The hobo spider lays its eggs in September and they hatch during late spring. After the male hobo spider mates it dies. Taxonomy The species was first described in 1802 by naturalist Charles Athanase Walckenaer as ''Aranea agrestis'', in reference to its western European habitat in fields, woods, and under rocks. In 1841, Walckenaer transferred the species to the genus ''Tegenaria''. In 2013, ''Tegenaria'' was split up, and the hobo spider was transferred to a new genus ''Eratigena'', an anagram of ''Tegenaria''. Identification Spiders, inc ...
