Hello,
As a matter of fact, the
Laboulbeniales don't kill their platform. Logically, there must be some exchange between both organisms, but I have seen many Coccinellidae with such fungi.
Here is another instance:

Hi all,
It is generally accepted that Laboulbeniales are parasites: they cannot survive without nutrients of their host and there is no evidence of the host receiving something in exchange. However, no precise experimental data on the nutrition of the Laboulbeniales is available.
Although mostly no real severe damages are observed, there are some records of Laboulbeniales harming their host (e.g. lowering the number of offspring).
Typically
Hesperomyces causes deformation of the exoskeleton, because it penetrates the host’s integument with a haustorium. Haustoria make contact with the host’s haemocoel and draw nutrient material from it.
