It does appear to be Cordyceps Craig

, note the stroma rising up form the abdomen of the moth in the second image and in the first image they are much smaller. Cordyceps affects different insects in different ways. Ants for instance will have a stroma rising up from the back of their head after the fungi has killed them, the grasshopper in my post some months back, show stroma rising form various places and joints around the grasshopper, on your second moth, the stroma is rising up from the abdomen it appears and the stroma are much different from that on the first moth. Cordyceps is very diverse in its species and effects, we could go on and on as to how it affects different insects. I will be keeping a close eye out for fresh specimens this spring and summer, though the pics will be grusome, they will probably fascinate as well, if I get them.
