My friend snapped this photo of slow-moving flies in clusters on a tomato plant on an August, ”fairly humid” day in Canada (I didn’t know Canada had warmth or humidity). They must be Lucilia (seracata?), but what are they doing?

We are familiar with single Flies being overcome by a fungus infestation (see BugGuide), but this group cemetery is a bit of a mystery that alas, we cannot immediately research as we have already spent far too much time at the computer this morning and we must attend to a few things before leaving home to teach California college students. Perhaps there will be a comment or two on this posting when we return.

I’m betting it is still fungus-related, but the bottom line is I have no idea. Maybe the person took images a few hours (or a day or two) later, and then the fungal spores would have been visible?
