Your letter to the bugman:  Found these holding three logs together in my woodpile today, 3.10.19. Not sure if it’s fungal or insecticidal. The woodpile is seasoned and covered. It’s been that way for about 2 years now. Ever seen it?

Fungus we believe

Dear Paul,
We do not think this is insect related.  It looks to us like a Fungus.

Slime Mold

Dear Nicholas,
Because we just identified another example of Slime Mold from Oregon, this was a very easy identification for us.  According to the Agriculture and Natural Resources University of California site:  “Slime molds, classified in the group called Myxomycetes, are primitive fungi that feed on dead or decaying organic matter and have elaborate life cycles. The mature fruiting bodies of slime molds are quite diverse and can appear as sheets, mounds, crusts, blobs, and even eggs or structures of insects.”  Smug Mug has numerous similar looking images.

Your letter to the bugman:  At first I thought this 4-tine garden cultivator had rusted solid from being left outdoors, but upon closer inspection I realized it was entirely covered in dark orange eggs! I think they might be moth eggs. No eggs were present on the wooden handle.

Slime Mold we believe

Dear Pam,
Thanks for sending in this fascinating mystery.  While these red “things” do seem to resemble insect eggs, we have our doubts because of the varying size of the individual “eggs.”  We would expect much more regularity in the size of eggs.  Here is a somewhat similar looking image of Slime Mold that we found online and Dave’s Blog has a similar image.  We also found Slime Mole images that look similar on FlickR and on the University of California Agriculture and Natural Resources site.  We are inclined to identify them as Slime Mold.

Slime Mole we believe

Oh wow! Thank you so much, I would never have considered a mold, I have never seen anything like it before!
Also, Thank you so much for your blog, I have been using it to identify random “bugs” that I have found for over 10 years, starting when I was just a teenager. It has been an invaluable resource for me.

Your letter to the bugman:  Hello, I have a vivarium for Poison Dart Frogs and found some small white nodules growing under a piece of wood. My hope is that this is some sort of fungus or mold. But my concern is that these are the eggs of some bug that could do harm to my frogs or their eggs.
The piece of wood was harvested many years ago from a forest in Ontario. I included a picture of the wood with suspicious object, as well as a picture of my cute frog!
Happy Holidays

Growth in Dart Frog Vivarium

Dear Jason,
These do not appear to be eggs, and we believe your suspicion that they might be fungus or mold is probably correct.  Friends of ours in the Los Angeles area formerly bred Poison Dart Frogs.  They had several pairs that bred in bromeliads, but alas, the vivariums were discovered by invasive Argentine Ants that killed the frogs.

Your letter to the bugman:  I have found several of these flies on my pepper plants. I am unable to find any information about them. They seem to attach themselves on the leaves with almost a web like thing and than die. Or something. Not really sure.

Fungus Ridden Fly

Dear Courtney,
Flies and Parasites are not mutually exclusive as there are many parasitoid Flies, including Tachinid Flies.  These are Flies, and they have been infested with a fungus infection.  Here is a similar looking BugGuide image, and your Flies also appear to be Blow Flies.  Many creatures, both plant and animal, can get fungus infections and BugGuide has an entire section devoted to Fungus Ridden Flies.

Your letter to the bugman:  Hi Daniel,
I was poking around my patch of common milkweed today and came across this most peculiar looking creature.   Looking at the enlarged image, I believe this is a spider.  What I am not sure of is if it has been parasitized or if this is some sort of disguise?  I’ve never seen anything like it and hoping you can shed some light on what it is.

Spider with Fungus Infection

Dear Deborah,
You are correct that this is a Spider and you are also correct that it has been parasitized.  This Spider has expired from a fungus infection like the individual in this BugGuide image and this BugGuide image. 

Thank you for the response and the links.  Interestingly, I found a second spider on the same milkweed that was also dead, but looked more like the photo in the first link.  I wonder if the milkweed plant is carrying something that affects the spiders.
Deborah Bifulco

While we would not rule it out entirely, our suspicion is that milkweed and the fungus are not related.
