My sundew caught two little fruit flies. One of the leaves moved it to the center and pressed it to the center, but did not wrap itself around it. Is this because it is small? And is it digesting it? The other leaf moved it to the center, but the fly doesn't look like it's pressed against the digestive part of the plant. I didn't know if I should take the fly off of their......or if it will drop it if it doesn't want to eat it. If id does eat it, does it drop it off of their, or does it stay stuck in the "dew"? Thanks.
