On Friday, I witnessed this battle outside on diningroom window. A stinkbug was basking in the sun against the glass doors, when I tiny spider descended upon him really fast, and bit into the bug. The bug started to kick and struggle, but it was to no avail. After about 45 minutes, it was finally over and the bug kicked no more. The spider then proceeded to carry the bug off.
I was surprised that the bug did not use its trademark odour to deter the spider, or maybe it was just a very determined spider.
