  1. Arp, any backstory on the life cycle of this fungus? Posted 3 months ago
    1. Not much time but I'll dig up a PDF or two and add them to the references of the species description

      Here's one for starters:

  2. Awesome shots, Arp! I found this for the first time last summer!
    Hesperomyces virescens on Harmonia axyridis This ladybug has a parasitic fungus, Hesperomyces virescens, growing on its elytra. The fungus spreads during mating and through encounters with infected ladybugs; it can easily spread among ladybugs overwintering in groups. Despite the probable discomfort and sometimes impairments to movement, most infected ladybugs lead full and happy lives.<br />

    1. Yes, in fact, stumbeling on that one made me realize I could add some too, but only had these at hand on the laptop travelling with me in these nomadic months though ... Posted 3 months ago, modified 3 months ago
