Moved to Tegenaria atrica

Moved from Spiders. Based on range this does appear to be T. atrica. Nice!

Moved to Spiders

Moved from ID Request. I'll have to wait until next week before I can look through my references.

Unsure

I was thinking about this again, and I may have jumped the gun. While the leg span sounds too big for T. domestica, the body sizes seem pretty small. Now I'm not so sure which this is. Best to wait for word from the experts.

Body size revised

I've been told my body size estimate is off by the other person who saw and handled the spiders. The one in the glass is closer to a half inch long body. The larger one which I couldn't get a clear picture of was closer to 1 inch in length and had a leg span of almost 5 inches fully extended and the third was approximately 3/4 of an inch with a leg span of approximately 3.5 inches. These new estimates are based on the one inch wide stripes on our drapes where the largest and second largest spiders were sitting - we measured the width of the stripes.

body size estimate

Keep in mind, my body sizes are just estimates. Since the mouth of the glass is exactly 2.5 inches wide and the smallest of the 3 (and the one photographed) is the only one that fit into the wine glass (with it's legs bent) it's only the leg span that I can be fairly accurate with.

Yes, funnel web

An adult male funnel web spider in genus Tegenaria. They are often found wandering, looking for females. Can you give a size estimate? I'm thinking this may be T. atrica (T. gigantea's range doesn't include NS from what I know), which would be cool since we only have two other images of the species in the guide.

size

The leg spread of the spider in the photo was the full width of the mouth of the wine glass which is 2.5 inches across - at least with it's legs bent a bit. The second identical spider I found today (sorry no photo) was double that size - I couldn't get it in the wine glass without harming it so I stopped trying and did not have another clear glass container handy with a wide enough mouth to contain it. The third identical spider was pretty much right in between the two sizes. With respect to body size, the spider in the photo was approximately .25 of an inch. The large second one was at least .5 of an inch and the third fell somewhere in between.

Size

Awesome! I think this is likely T. atrica then. Let's see what others say.
