Yes, I am excited to see Dung Beetles in our pastures.
Yes, I know that many people may think this is an odd thing to get excited about… but it’s because they don’t understand what it means.
To me, this says our pastures are turning a corner from dying to living. From degenerating to regenerating. It means we are moving in the right direction!
Let me briefly explain. Many farms across the world are dead or dying. Farmers, with good intention but poor knowledge, spray synthetic fertilizers, herbicides, fungicides, and pesticides. This kills the creatures that live in and off the soil. This ultimately kills the soil, and this ultimately kills the farm. Yes, it is that simple, and it is that vital! As we stop killing the biodiversity on our farms, our soils can come back to life. The pastures become more healthy and more resilient… and the farm follows.
The Dung Beetle life cycle is relatively straightforward. They lay eggs into dung (i.e. manure). The eggs hatch, and the larvae consume the nutrients found in the manure. The larvae pupate into adult beetles, and the cycle repeats itself. Some Dung Beetles directly bury the manure; this means the adult beetles dig a hole straight through the manure pile into the soil. They take the manure with them into either shallow holes or deep holes depending on the species. We can identify the presence of direct burrowers by seeing manure piles with a bunch of holes in it. Other Dung Beetles are rollers. They make a dung ball and roll it to another location. Once at their desired location, they dig a hole and bury the ball.
Dung Beetles perform multiple beneficial functions on a farm. They bury massive amounts of nutrient rich manure into the soil. This alone make them hugely beneficial. Also, since Dung Beetles can make a manure pile disappear within a few hours to a few days (depending on numbers and size of the pile), this reduces the ability of other insects, like annoying and disease spreading flies, to use the manure for their reproduction cycle. Dispersing the manure also helps break animal pest and parasite cycles. From an aesthetic viewpoint, when manure piles are quickly dispersed, smells are also quickly dispersed. And walking through pastures with large numbers of Dung Beetles, means guests and kids are less likely to get manure all over their shoes.
Dung Beetles are a fantastic marker of pasture health, and therefore, soil health. They are very sensitive to chemicals sprayed into pastures and used on animals (cattle, sheep, etc.). These chemicals directly kill the adults or indirectly reduce Dung Beetle numbers by destroying eggs and beetle larvae. All the benefits listed above are lost. I can’t tell you how many conventional farms I have been on where there are dried piles of cow manure that have been sitting on the surface of the soil for years. These big, concrete-like frisbees are glaring markers of poor soil health. This is what covered our pastures when we moved to our farm just over a year ago.
Maybe now you can see why I am so excited to see Dung Beetles on our farm!
