Hey lehua13,
It looks like a squash bug or a stink bug. Google them both and see for yourself.
Also, google spined soldier bug. If your bug is a ssb.... I read somewhere that they are beneficial for the garden. Hope this helps.

Thanks Charito,

It sure is a Stink Bug (spined soldier bug). Unfortunately it seems Stink Bugs come in two classes eating other bugs or eating plants including Citrus. I will give this bug the benefit of the doubt until I see some damage. I do not want to use pesticides, but if this bug attacks the fruit that may be another story. Next time I will photograph from above. It seems most bug photos are from that angle for identification. Thanks again.

Take a bucket of soapy water and knock the down in the solution. Dawn works good. Where they puncture the fruit will cause a bad section.

Thanks Pecanman,

I haven't seen any other bugs like this one so far, but my soap bucket is ready for action. I did venture after dark to see what might be hanging around my plants. I didn't realize Black Widow Spiders came out at night and weaved webs. I found over ten around the perimeter of my house! One was right next to where my running shoes are kept by the door outside. What a surprise that would have been.

It is a squash bug, also known as a stink bug. When squashed it smells very bad. They carry virus and bacteria that will wipe out most cucumber plants in a few hours. At the stage your picture shows, they are almost immune to chemicals. Hunt them down and send them to their maker...LOL. Wash them off plants with spray hose and kill them before they hide again. They stay on the underside of leaves and hide out while sucking on the plants. When the suck they infect the plants. If you are raising squash, melons, or cucumbers (Cucurbitaceae family of plants), select only disease resistang varieties to reduce plant loss. Good luck!

Thanks J,
It looks like so many bugs good and bad. It is very similiar to the Brown Marmorated Stink Bug, very bad and also the Spined Soldier Bug, a predator. I just have to get a better picture of one. I don't have cucumbers or squash planted, but the BM Stinker attacks fruits and veggies plant or fruit. I am watch closely for another shot at one.

I've been studying this guy and can't decide which is which, either! I appears to have a long proboscis, which would be found on the predators, though. But I might be seeing things. ;-)

I dont see the long probiscus unless it laying back underneath the head. This is a link to the Spined Soldier Bug (podisus):

This is the link to the Brown Mamorated Stink Bug:

I can't decide either. I will try to send this to an expert to identify. But I think the angle of the picture makes it hard to say.
