Recently I did post a question on gardening stackexchange asking if cabbage worms could smell their way back into my cabbages after I moved them away outside my fence. Answers says yes they do, but it seemed to me opinion-based and I cant find anything to support this answers.

Can this type of worm smell/see or have any other type of sensorial navigation thing that can lead them towards cabbages?

  • $\begingroup$ Yes, caterpillars have antennae that provide an olfactory sense. I don't know how well this particular caterpillar can smell and if it can travel long distances, but it is able to identify its food source. $\endgroup$ – Roland Dec 20 '17 at 13:15
  • $\begingroup$ I don't understand why you are asking about the caterpillar? The most important way the caterpillar ends up at your plant is because the butterflies deposit their eggs. $\endgroup$ – RHA Dec 21 '17 at 10:01
