Symbi Biological


Crickets have been added to the Fish Food Project. Our friends from Bitwater Farms¬†set us up with a sweet little cricket habitat. This is really exciting to have another protein source to use as we develop our own fish food for our aquaponics system. You know, I think the chickens are going to think they’re pretty tasty, too.

Pupa Walk

Here’s a pupa “walking” under a 15x lens. They’re kinda cute, huh?

Surprise! More Pupae!

What a pleasant surprise to be greeted by some over wintering larvae! These hardy souls have been kicking it in this flat of compost and soil waiting for their time to emerge. I put the flat there next to the Biopod thinking it might be a good place for them to crawl out and land. Since the greenhouse doesn’t have any soil, just some empty benches, I put some potted plants and this flat inside to give them somewhere to go.

Well, they went there! And they’re still in there! The warmer temps have given them reason to rise and I’m looking forward to having some adults around. While I’m hopeful the very young larvae that are in the Biopod are BSFL, it appears we’ll have another crack at trying to induce sexy time and get some more babies.

Larval Dance

Here’s another shot of the new larvae. They have a certain grace to them. I sure hope they’re the good guys, but it’s hard to tell. I could be raising stable flies for all I know right now! As mentioned in previous posts, they still smell like soldier flies. They’re so small I used a 15x lens for this video. EDIT: Dang things are fungus gnat larvae. Leaving this post up because I think the video is neat.

BSFL Babies or Imposters?

We have some young larvae squirming about in the Biopod. Not really sure if they are another kind of fly or BSFL. They’re pretty small. At first, I just thought they were fungus gnat larvae, but I don’t see the typical black head that makes them fairly easy to identify. The bin also smells like the familiar Black Soldier Fly Larvae smell so maybe these guys are the real deal. We’ll have to wait until they grow up a little more to find out.



The system is at 53 degrees F. Things grow sloooowly in these temps. What’s interesting is that the water loss from the system is minimal. Read More

Dung Beetle Search: Aphodius fimetarius

A couple of days ago, I was flipping some cow pads to see what kinds of dung beetle activity we have on the ranch. I found Aphodius fimetarius, which is a European dung beetle that was brought over to North America by the settlers presumably.
