Some body is eating our squash bugs…

Living in the Southeast US, one of the tragedies of organic gardening is that growing zucchini is very difficult. This year’s zucchini wars have been very successful – we have gotten some squash! We started squashing adult Anasa tristis, the squash bug, in late May. Finding A. tristis egg masses has been a very common thing in our garden, but it is very rare to find nymphs.

Our garden has had many Coleomegilla maculata adults and larvae – perhaps they are eating the A. tristis eggs?

Kelly found a wasp (Sphecidae?) eating Ceresa festina (same family, Hemiptera, as A. tristis) in the garden – perhaps this wasp has been cleaning up the A. tristis nymphs? Or perhaps the two predators are synergistic? Possibly there may be fungus that is taking out the A. tristis?

All I know for sure is I had zucchini for dinner and the garden is working right this year!

    Nice! I’ve lucked out so far, haven’t seen a single squash bug yet with 9 summer squash plants and a pumpkin’ going strong.

      Part of the fun of gardening is the insects!
      We have also had visits from the sesiid, Melittia cucurbitae, but no real damage… yet. Hopefully my favorite squash pest, Epilachna borealis will show up soon. I hope some cool insects find your squash soon!
