A Mother Fly

She was a beauty, about ¾ inch long, lovely colour and undamaged by her eventful life, no dents in her eyes or broken hairs on her face. In fact she was the picture of health, as I know a fly can be.

This huge fly found its way into the laundry the other day. It was on the window glass and I couldn’t induce it to have some honey and slow down. It had other things on its consciousness, demanding its attention.

I followed it around for a while trying to get a decent shot of it, even moving. Eventually I decided to trap it in glass and that worked. After a few minutes under the glass it stopped still, so I lifted the glass and it remained calm. It climbed up the side of the glass and sat there for a while.

After a short time it tried to fly away and fell to the window sill, buzzing around on its back, wings beating loudly against the surface. I remember big flies doing this from when I was younger, much so.

I noticed its behind was white and I took shots of what was presented to me. When I looked on the LCD I could see tiny grubs and it clicked. It was a she and she was giving birth.

There were many, maybe 100, of these grubs scattered around the buzzing mother. It appears the fly goes a little manic with the readiness of birth which causes her to scatter her young. That would be better than to leave them all in one place, a ready meal ensuring an end to her line, not very evolutionary that.

Then, a little time later, she died.

And that’s the way of it here.

    Are you sure? Wake me in the middle of the night and I tell you that flies lie eggs on things, not give birth.

    Here, googled this: “L. sericata begin their life cycle by laying a mass of eggs in a wounded area, a carcass or corpse, or in necrotic or decaying tissue.” (from wiki: http://en.wikipedia.org/wiki/Common_green_bottle_fly )

    So most probably what you’ve captured here is some parasites and probably the cause of death?
    Possibly something’s just hatched inside of this fly?

      No, I’m not sure. Whatever it was it didn’t survive in the dry landscape. I left the dead fly on the window sill and visited it daily for a while and if it was parasites it chose a poor host, or just didn’t make it to the next stage of life, nothing further emerged – that I know of. She gave birth, though perhaps not to her own.
