These little grubs, have taken over one worm farm.. about 15 to 20mm (1/2>3/4") long

Whereas worms seem to leave a fairly nice tailings, these grubs end up with a thick sickening"Soup" that just churns with all the grubs..

I suspect any worms have died..

but the fish like them

looks like a BSF - not seen one that close up before!

BLACK SOLDIER FLY

I had NEVER seen one, but you seem to be right...

now I know what you guys have been talking about, thinking they did not exist in Oz..

Yep - I keep finding them everywhere other than in my BSF farm !

BSF larvae. Lucky you. They love worm bins and compost heaps. I had seen them in my compost long before I knew what they were. Now I breed them for chicken feed

The odd thing is that they are in a sealed[ish] worm farm..
There are zillions of them but I have never seen an adult, so they must reproduce as just grubs..

Now thinking of making a farm to correctly harvest them.. :-)

The adult flies canl lay eggs around the edges that can fall in , or if it was left with the lid not fully sealed one time they can get in. They are only active in summer where I am (and you are I presume)

Keep an eye out for the adults, you will probably see them around but they don;t tend to bother humans at all.. Heaps of info on farms and harvesting them around the forum, they are great because they self harvest when mature..

..
and if anyone wants some, I suspect they would post OK

Here is someone who would like some...
