A photo of Shannon SaiaLast year, my first year growing potatoes, I had a big problem with Colorado Potato Beetles.

This may have been because the first time that I saw them, I was captivated. I mean, they’re beautiful insects. I noticed them, I admired them, I watched them a little, and then I went off, leaving them to their business.

Big mistake.

Because not too long afterwards, when I was out inspecting, there were not only adult beetles, but this.

Shannon, That's awesome! I've never had a problem with Potato beetles, and over the last two years my potato patch has been much larger than in past years. - I have 75-80 plants - I've been watching carefully because I figure growing that many plants should attract some of them but it hasn't. Now I may know why. We always have wild sunflowers that grow intermingled with our potatoes. These attract aphids, and with those aphids, we get Lady beetles. Last year we had thousands aroung the garden I think. That must be helping I think. Thanks for the great info and very good pics too. I'll make sure to thank the ladies as well! Paul~

@Shannon, I think it’s great any time we can balance nature with nature. We got our first wave of Japanese lady bugs last year. I don’t even know if they are related to the lady bug but they look almost identical except for a difference in the number of spots and teeth. The Japanese lady bugs can bite. It feels kind of like when being bitten by a fly. I’m not sure what they eat or if they are beneficial but I know we had lots of them last year. I haven’t seen any lady bugs this year Japanese or American. However, I haven’t had any problem with bugs (Well except for mosquitoes). With all the rain we have been getting those skeeters are huge. I’m glad to hear that the ladies of the bug world have taken care of the dad blasted ol’ Colorado bugs. My potato plants are looking good. I inspect them quite often and so far haven’t found any bugs of any kind. I plan on rotating my beds each year so hopefully there won’t be a problem with bugs or diseases. Well that’s my plan. Dumping several inches of new compost on each bed may have helped some as well. Well here’s to a good crop of spuds in 2010 (raising coffee cup). Thanks for giving us a heads up about lady bugs.
