Today while picking pole beans I spied a recent hatching of something. I ran to get the duct tape, made a circle of it sticky side out and used that to blot up most of the little buggers. Stink bug babies. It's that time of year.
So I pulled up my stink bug sites to see which one they are and they're the southern green stinkbug. I thought I'd post the two sites here in case anyone else can use them.

These are the ones I discovered two days ago on the big bean trellis. There were two groups of them. Baby southern green stink bugs. Now FORMER southern green stink bugs.
![]() ![]() Near the babies was a bean with eggs on it. It's now in a jar by my desk so I can watch them hatch. That may not be far away as I've read the eggs turn from white to pink as they near hatching. Yesterday all the eggs were white but today only a few are. ![]() |

Here's a handy link with the various stink bugs and their developmental instars.
https://duckduckgo.com/?q=Stink+Bug+...ages&ia=images It's amazing how bugs change shape and coloring as they go through their growth stages. Their eggs change colors too as they develop. Stink bugs are in the order of Hemiptera and have that characteristec shield shaped scutella behind their heads. Beetles are in the Coleoptera order and don't have the scutella as part of their thorax. Last edited by GoDawgs; May 14, 2021 at 07:21 AM. |

Like something from Alien! Make sure the jar lid is on tight!

Thanks for the photos and links Godawgs, will have to check them out more fully shortly to see which one has migrated to my garden. One of the mongerals has that's for sure.

The stink bug eggs were white on Jul 8, then turned pink by Jul 10. Today they're starting to hatch.
Hmmm, what to feed them. Since they were found on a bean and since the babies were on the beans, I guess they'll feed on the bean in the jar. I love watching stuff like this! ![]() |

On July 12th the stink bug eggs hatched. Since then the babies have been just an inert cluster sitting on top of the empty egg casings. Today they're starting to move around and some are climbing the sides of the jar. The line of tiny white things along the left side of the bean are the empty egg casings.
![]() I got one out of the jar and put it next to a ruler with millimeters showing for reference. This little one has the same markings as the batch of larger ones I duct taped off the bean plant. ![]() |

I never would've thought these were stinkbugs, but after reading this thread, I think that's what I found today. Ugh. Currently battling stinkbugs, hornworms, grasshoppers, birds, aphids, and who knows what else for the tomatoes. Thanks for this educational thread.

I have to report that all the stink bugs in the jar have assumed room temperature and their mass casket, the jar, will be buried in the trash can forthwith. Maybe they sucked all the nutrition out of the bean that was in there. Anyway, it was an interesting experiment while it lasted.

They look similar to harlequin bugs.

ick! I never thought of using duct tape -- I prefer a container of soapy water. Nice experiment.
I'm getting lots of stink bug damage on Rose Quartz Multiflora and Arkansas Traveler, but so far have seen only one bug, and it was too dark to try to catch it. One of these days, before I start seeing too much damage on all the other varieties, I will have to scout the whole jungle for eggs and juveniles! |
