Well it may be graphic for some but not others, so I put that in the header just in case. There is no telling what you may come across foraging around in the woods for subjects. I had just about given up on finding any thing more having being infected with the fungus, however unexpectedly I found this, this morning on a leisurely walk. As one can see it has been there for quite sometime attached to a Poplar sapling.



The head of what ever this was, has long since been removed due to weathering and looking closely, the stroma can be seen protruding from the various joint segments and along the abdominal segments.



Seems as though there is one very large stroma about midway of the abdomen and at the posterior of the carapace, what appears to be an ovipostor, maybe but then again maybe not but some other sort of appendage.

Excellent find Ken. You always find the cool stuff. I think Jim needs a refresher on what Cordyceps is. It is amazing how tuff that stuff is Shocked

This was or could have been at one time, a grasshopper, cricket, or maybe even a katydid, judging from the hind quarters there. Cordyceps is a fungi, one that is used most commonly in the field of medicine for treating heart transplant patients, it hinders transplant rejection and probably has similar uses elsewhere, though I am not up on all that stuff.

Anyway this insect has ingested one of the fungal spores and upon spore germination, it begins to take over, from what I can gather, the insects nervous system. The fungi compels the infected insect to climb to sufficient height, be it on a tree, a shrub, fence post, or a blade of grass, once sufficient height is attained, the insect will fasten itself to the substrate, in some instances by its mouth parts or other appendages. Then the fungi produces the fruiting body or “stroma,” which you see as spikes erupting from the insects exoskeleton. These spikes will burst at the tip releasing more deadly spores into the wind.

Most commonly I find numerous ants that have been infected and from what I have read the fungi can wipe out an entire colony in no time. If you want to really see how strange this fungi is, watch this . Very Happy
