You now have a total of 9 pts. And so on. Some families have hundreds of species, and you will encounter several. For every 5 you collect of the same family, you get an additional point, unless they are the same species. You don't have to identify them all to species to get the points, either.
Most taxa are only identifiable to family or subfamily without intensive library work.
Groups such butterflies and moths require special preparation. To encourage you to include these in your collection, properly prepared specimens are worth an additional point. An additional bonus is that it is often possible to identify these to genus and even species without too much hassle. Labels are easy to make and attach, so a strong penalty will accumulate for a shoddy collection. There is a very good chance that you can gain back a whole letter grade with some extra work on the collection.
