Dear Alfred,
This intriguing spider is an Arrow-Shaped Micrathena,
Micrathena sagittata, and according to BugGuide:  “This spider does not pose a danger to humans (and neither do any others in this family).”

Thanks for that!  I did actually find that eventually but nice to have it confirmed.   Beautiful spider I have not seen before.

Dear Scott,
Thanks for letting us know that you were able to identify your Golden Orbweaver,
Argiope aurantia, one of the Writing Spiders, by searching our archives.  We appreciate you letting us know that we could cancel your request, however, your image is quite nice and we haven’t posted a recent image of a Golden Orbweaver, so we have posted your submission.

Thanks Daniel, I am honored to be on your fantastic website!

Subject:  What is this large spider? 2nd request
Geographic location of the bug:  Northeast Maine

Your letter to the bugman:  Hi. I found this large spider after a heavy rain on north side of my house – early evening. It is at least 3 inches with legs. It is huge and rather scary. Some research leads me to believe it is a fishing spider and that it is not dangerous… I would love you to confirm that.  I saw it again on a darker evening  – I thought it was a small mouse it is so large… we live in a wooded area with a small brook.

Fishing Spider

Dear Dianne,
You are correct.  This is a harmless Fishing Spider in the genus
Dolomedes, most likely the Northern Fishing Spider.

Subject: What’s this Hopper on my Cannabis?
Location: Mount Washington, Los Angeles, California

Subject:  Hi Bugman,
As my Cannabis plants grow larger, I’ve noticed that many of the plants have predators on them.  In addition to the Mantid I submitted earlier this year, I am happy to report that four of my plants have mantids on them and several have Green Lynx Spiders as well.  Can you please identify the hopping insect that I have found on my plants this year.  One of the images of the Green Lynx Spiders I am sending has it eating an immature hopping insect, though it is difficult to see.  The other image is of a winged adult.

Green Lynx Spider eats (presumably) Glassy-Winged Sharpshooter nymph

Dear Constant Gardener,
Thanks so much for keeping our readers informed about your thriving
Cannabis ecosystem.  The adult hopping insect is a Glassy-Winged Sharpshooter, and according to BugGuide:  “The biggest problem is that it can spread the disease-causing bacterium Xylella fastidiosa.  The most important biocontrols are egg-parasite wasps in the genus Gonatocerus. Spiders, assassin bugs, and praying mantis prey on the mobile forms.”  Several years ago, we received a report of Glassy-Winged Sharpshooters, Homalodisca vitripennis, on marijuana.  According to the University of California Integrated Pest Management Program site:  “The glassy-winged sharpshooter is found in many habitats, including agricultural crops, urban landscapes, native woodlands, and riparian vegetation. It feeds on hundreds of plant species across dozens of plant families. Hosts include numerous common woody plants as well as annual and perennial herbaceous plants. It is common to find this insect on acacia, avocado, eucalyptus, citrus, crepe myrtle, heavenly bamboo, grape, photinia, pittosporum, hibiscus, periwinkle, xylosma, some roses, and many others. Host preference changes throughout the year, depending on the availability and nutritional value of host plants. Some hosts are preferred for feeding while others are preferred for reproduction. Irrigation level and fertilizer additions can also impact the attractiveness of hosts for sharpshooters.”  There is no mention of Cannabis.  We presume the nymph being eaten by the Green Lynx Spider is a member of the same species.

Your letter to the bugman:  Found this “little” guy in my house he’s about 4 inches in diameter its currently summer here in AZ. He was climbing the wall. Didn’t find a web or eggs. We get a lot of crickets around here so that may be his diet.

Male Cellar Spider

Dear Gaston,
This appears to us, based on this BugGuide image, to be a harmless male Southern House Spider, a harmless species that is often mistaken for the highly venomous Brown Recluse.

Update:  Cellar Spider
Cesar Crash provided a comment indicating this is a member of the genus Physocyclus, a Cellar Spider, and this BugGuide image would support that identification.

Your letter to the bugman:  I found this lovely spider on my Siberian iris this evening. I can’t tell but it looks like she’s eating an ant, maybe? I’d love to know the species of spider as I haven’t seen one like this. Thanks!

Western Lynx Spider eats Ant

Dear Sheryl,
The spiny legs and shape of the body reminded us of a Green Lynx Spider, and we quickly identified this Western Lynx Spider,
Oxyopes scalaris, thanks to images on BugGuide
