Subject: Poisonous to Humans?
October 11, 2014 3:37 am
I just had to destroy all my Tomato plants because of a mass infestation of HUGE  Leaf Footed Plant
Bugs. There were 7-8 of these bugs on ONE Tomato–many Tomatoes.  I only had 7 Tomato Plants in containers, but they COVERED them all. I live in the desert of Las Vegas, Nevada, and everything I’ve read about them says they are not on this side of the country! The Nevada Extension says they are rare, but not unheard of.   They are now on my Bell Peppers, though not nearly as many.
However, I cannot find out if the toxic enzyme that they inject into the fruit , also allowing pathogens into the fruit safe for human consumption.  I can’t see any obvious damage, and I am very diligent about keeping them off the Bell Peppers.  I don’t want to get myself or family sick. Do you know if they’re poisonous?
Your quick response would be greatly appreciated.     Thank You,  Diane Huff

though the damage to fruit is unsightly, and probably does not taste very good, to the best of our knowledge, the enzymes injected will not negatively affect the health of a human.

Dear Mr. Marlos,
Thank you so very much for your VERY quick reply!  You’re the first person to commit to any other reply than, ” I don’t know”.
I feel much better about preparing my family a Stuffed Pepper dinner, with a salad containing raw peppers.
What do you know about “Anthracnose” fungus on Bell Pepper leaves? I know that’s not a bug, and I see NO lesions on the peppers
like I see in all the photos that I’ve researched online.  The small damage is only on the leaves and maybe a tiny bit on a mark
on a very few of the peppers.
I probably have no right to ask you about fungi, but all I get everywhere else is “I don’t know”. If you do not, I figured it couldn’t
hurt to ask, could it?      Sorry if it is…
Again, I thank you so very much—you’re the best!!!

Hi Diane,
We actually gave you a very quick response without any research, and now we feel we need to remedy that.  We hunted our archives to find appropriate images to illustrate your questions since you did not provide any images.  We can tell you that we personally have eaten pomegranates that fed Leaf Footed Bugs, and we did not suffer any ill effects, though we did not eat the parts of the fruit that looked bad, dried out and generally unappetizing.  We have been buying oranges that are eerily dry in some parts, and we suspect that Leaf Footed Bugs might be the cause, but since we just juice the oranges, and we don’t have to eat the dried parts, other than getting less juice from an orange, we haven’t noticed a difference in flavor.
  We don’t know anything about the fungus, but perhaps one of our readers will comment.

Subject: Another example of Tachinid Fly with Fungus Infection??

Hi all,
I think this is another example (found 6th October 2014) of a Tachinid Fly with the pathogenic fungus Enthomphthora Muscae, it just looks as if it flew straight into my back door and died on impact. Possibly the same as on your web page:  http://www.whatsthatbug.com/2009/12/25/tachinid-fly-we-believe/
Can you please confirm that it is a Tachinid Fly? As I don’t believe there are any ‘natural’ black and white stripped fly’s here in the UK that look like this one.
Kind regards

Hi Millie,
We agree with both your identification and your diagnosis.  As Karl indicated in the link you provided:  “There are numerous photos on the internet that look very similar to this this. The white banding occurs as the fungus bursts out between the abdominal segments (presumably just before the victim expires).”

I’ve looked to see what my little alien being was called and have seen old posts of fuzzy pictures. So i figured for the sake of science and imagination! This guy was hanging from a web. I’m almost positive it’s dead.

We’ve got them too!
We have an 103 year old four square and found them in the basement cellar under the porch. We never go there, but we went down there when we found a chipmunk coming in and out from our porch foundation. We went down to flush the chipmunk out and fill in the hole when we discovered these fascinating creatures … albeit creepy!
We live just south of Madison, WI
We had never seen them before.
We have the same questions as everyone else.
Why is this fungus suddenly appearing?
And, is it harmful to humans?

These are probably the best images we have received of Cellar Spiders infested with a deadly fungus.

Hi , my name is Justin I collect insects as a hobby and have taken a couple entomology classes, but I can’t ID this insect. It looks like some sort of a longhorn beetle . But I believe this is husk or shell. Is this possibly a nymph stage of an insect? This was found in November 2013 near Gaitlinburg TN USA.

Unknown Katydid Nymph

Fungus Infected female Carolina Leaf Roller

Hi Justin,
WE are having trouble providing you with a definitive identification, but we can tell you this is not a Longhorn Beetle.  This is an Orthopteran in the suborder Ensifera, the Longhorned Orthoptera.  Furthermore, we believe it is an immature Katydid in the family Tettigoniidae, and the presence of an ovipositor indicates it is a female.  This does not appear to be a shed exoskeleton, as there is no evidence of a splitting along the dorsal surface which is where the newly metamorphosed insect would emerge from a cast-off exuvia.  Your image is not as sharp as we would like, and we are uncertain if those are spines on the body, or perhaps the remnants of a fungal infection.  There are several examples on the Field Biology in Southeastern Ohio page of Carolina Leaf Rollers infected with
 Cordyceps fungus that look very similar to your image, and we believe that might be an accurate identification.  The description on the site states:  “Another body invading fungus is Cordyceps. They are known to attack at least a dozen different orders of insects. This is a Carolina Leafroller, Camptonotus carolinensis, a katydid relative.  The dark spot at the base of the abdomen, and the long ovipositor verify this as a female leafroller. Cordyceps fungi may be more familiar to some with regards to ants. This is the same genus that affects the brains of certain ants, turning them into zombies. They climb to high points on vegetation, then the fungal spores spring out of their head. Infected ants are recognized by the colony, and individuals are removed so they won’t cause the entire population to die.”  So, after our research, we are concluding that this is a female Carolina Leaf Roller, a Raspy Cricket, that has been infected by Cordyceps fungus.

Gall

Cedar Apple Rust Gall

Dear K. Baer,
This is a Gall, which is a generic name for a growth on a plant.  Many are caused by insects, mites and other “bugs” but this is a Cedar Apple Rust Gall in its dormant state and it is a fungus.  Here is what the Missouri Botanical Garden website states:  “Symptoms on juniper: Brown, perennial galls form on twigs. When mature (usually in two years), the galls swell and repeatedly produce orange, gelatinous telial horns during rainy spring weather. The galls of cedar-apple rust are often over 2 inches in diameter, while cedar-hawthorn rust galls are rarely over 2 inches in diameter. Occasionally the twig beyond the gall dies, but usually no significant damage occurs on the juniper host.”
  The University of Missouri Extension website has more images and information.
