Yes, and this even applies to vertebrates and can sometimes work in reverse. I was part of a team of research divers that did fish counts in California. This was in the early 00's so in several instances genetic research found that seemingly identical fish were different species depending on region. In one case groups of fish that looked quite different turned out to be the same species. Very frustrating when you are putting in so much work underwater! That whole experience made me very skeptical of citizen-science projects once I knew how much training was required to do good work. While they are a great compliment to professional research they are no replacement (though often funders are treating citizen science as just that).
