So yesterday I collected more inchworms in a bigger jar. I also created this video.
in the garden, they really like the leaves of The Japanese Honeysuckle and that is where I find most of them. the brown color and the way they hide within the vines makes it hard to spot them, but once you know what you are looking for its very easy.
they produce a lot of feces as you can see in the pictures. they are small ball shaped.
