Ladybird Beetle - Harmonia axyridis

Ladybird Beetle - Harmonia axyridis
Moccasin Lake, Winston, Douglas County, Georgia, USA

I have no idea what this is on this Ladybird Beetle, fungus or eggs of some sort. Comments welcomed. Attracted to UV light.

Laboulbeniales fungus, Hesperomyces
This is a fantastic photo.

The fungus is a member of Laboulbeniales, under the genus Hesperomyces. Almost 100% positive it is Hesperomyces virescens as I do not know of other species that grow on Harmonia.

Hesperomyces occurs on all sorts of coccinellids (and a Scymnus from New Zealand), including Harmonia, Hippodamia, etc.

As for the rest of the pictures linked here that are on Harmonia, the infections are almost certainly all H. virescens.

Would be happy to help in IDs of Laboulbeniales in the future.

If this is the same thing, your specimen seems to have an especially abundant growth!

Hesperomyces virescens
In an email to me, mycologist Monica Hughes identifies this fungus as Hesperomyces virescens in the order Laboulbeniales (Ascomycota) and describes it as a very common species. At her suggestion, I searched the internet via Google for additional information, finding the following citation, very relevant to this BG posting:

Thanks to Dr. Hughes for this information!

Thank you
Very interesting articles and yes, the bug I photographed had more than it's share of fungus. On another note, it has been raining here in the deep south off and on for weeks. Maybe this contributed to the excessive growth of fungus on the Ladybird Beetle.
