Your letter to the bugman:  I found these two in a cup on my porch after returning from out of town after a few days. Someone told me they are mygalomorphae. My question is are they venomous/dangerous to man.

Trapdoor Spider

Dear Dan,
We suspect this might be a male Southwestern Trapdoor Spider,
Eucteniza relata, which is pictured on BugGuide, or a closely related species and then again, we may be wrong.  Perhaps one of our readers more skilled in arachnology will be able to identify the species.  According to BugGuide:  “Eutecniza males can be recognized by the presence of 1-2 mid-ventral megaspines on the tibia of both legs I and II” but we do not have the necessary skills to make that definitive identification.  Your amusing collection of Trapdoor Spiders, Longhorned Borer Beetles and Cockroaches is quite the still life.  Trapdoor Spiders may bite humans but they are not considered dangerous.

Your letter to the bugman:  I am a Huge bug fan!  I am a commercial photographer by day and a wildlife and macro photog for fun.  I cam across this little one in the garden last night and I had never seen colors on a spider like that..just wanted to see if it in fact was a Red and Green Orchard Spider.
So happy to have found your site!  It is AWESOME!

Dear Caroline,
You are correct.  This is indeed an Orchard Spider,
Leucauge venusta, and your image is positively gorgeous.  We hope you consider sending other high quality images of the insects and bugs you find.

Fishing Spider

Dear Amy,
This is a Fishing Spider in the genus
Dolomedes, most likely a White Banded Fishing Spider, Dolomedes albineusFishing Spiders get their common name because most species are associated with water and they are able to dive beneath the surface to escape predators as well as to hunt for fish, tadpoles and aquatic insects.

Your letter to the bugman:  Could you please help me to identify this spider? It is dead, but I think pretty recent as I used a pencil to extend its front leg and it didn’t break. I actually thought it was going to move. Found it on the living room floor. Size is about 1″ body length, front leg 1-1/4″ long. Approximately, didn’t not have time to measure it. Is it poisonous, deadly? Live in Southern Spain, Costa del Sol, less than 1 mile from the Mediterranean Sea. Any info can help. Do you think a family is near by?

Andalucian Funnel-Web Spider

Dear Debi,
The extremely long spinnerets on the tip of the abdomen is such a distinguishing feature, we had no trouble identifying the endangered Andalucian Funnel-Web Spider,
Macrothele calpeiana, on The Olive Press where it states:  “The Andalucian funnel-web spider is considered to be the largest in Europe and is easily recognisable.  They are jet black with a glossy carapace and fine hairs on their legs and abdomen.  The 1.5 cm-long spinnerets, at the rear, almost look like extra legs.  The body can be up to 3.5 cm long and the stretched legs can reach a span of 8 cm.”  The site also states:  “This is the only spider in Europe to be protected by the European Union Habitats Directive.  They are found mostly in Cádiz and Málaga provinces with smaller numbers in scattered enclaves discovered in Huelva, Sevilla, Granada, Jaén, Gibraltar and the furthest north Badajoz, in Extremadura.”  According to Wildside Holidays (where those prior two quotes appear to have originated) :  “These spiders are most active at night when they will wait at the tunnel entrance for prey to become glued onto the silken web. Their diet consists of small insects such as beetles, woodlouse, millipedes and crickets. When they feel the vibration of a trapped insect they will carefully approach, then bite the ill-fated prey with venom which will begin to liquefy it as they wrap it in silk. The venom is injected into their prey through openings in the tips of the pair of fangs. The glands that produce this venom are located in the two segments of the chelicerae. (The parts to which the fangs are attached).”  By the way, we are relieved to learn you discovered this magnificent spider dead as we did not want to have to tag your posting as Unnecessary Carnage.

Flattie

Dear Jakob,
This is a nocturnal hunting spider (does not build a web for snaring prey) in the genus
Selenops, commonly called a Flattie, and here is a BugGuide image that looks very similar.  According to BugGuide:  “This genus is found throughout the tropics and subtropics worldwide and can be found in southern parts of the U.S. ”  This shy group of Spiders is not a threat to humans.

Female (larger and on left) and male Golden Silk Spiders

Dear Joshua,
Look closely at the silk of the web and you will understand why the common name of spiders in the genus
Nephila is Golden Silk Spider.  The female on the left is about 50 times the size of her diminutive mate on the right.

Wow, so interesting.  Thanks for the quick reply.
Joshua
