                                          The Insect Collection


Requirements: There are no set numbers of orders or families required. Rather, you can gain and lose
points as described below. In calculating final grades, I will assume a perfect collection to be
worth 100 points. This can be achieved by turning in 14 orders and 79 families of insects, with no
misidentifications or points lost due to problems with specimen quality, preparation, or labeling. Note
that there is no upper limit (except for the number of insect orders and families on the planet), thus it is
quite possible to turn in a collection worth more than 100 points. In fact, it is relatively easy to do if
you devote the necessary time to the task. See the Insect Collection Guide for very complete
instructions for every part of the insect collection.

Due date: The insect collection should be turned into the instructor or the TA on the afternoon of
Monday, April 30th, between 1 and 5 pm in room 210 of Minnie Belle Heep. Please do NOT bring
your collections over to my office in the biological control building. At the time you turn in your
collection, you should also turn in your collecting kit, which will be inventoried on the spot. Please
note that failure to clear the return of ALL items in your collecting kit before final grades are due will
result in an Incomplete Grade for the course.

Preview Collection: A portion of your collection, representing 10 DIFFERENT FAMILIES, will be
due by March 28th (early submissions cheerfully accepted). The purpose of this preview collection
will be to provide you with an early assessment of your progress towards completion of the insect
collection, and to provide you with early feedback on your curatorial skills. Specimens must be
properly curated, labeled, and correctly identified to family and order (see Insect Collection Guide).
You will lose points for misidentifications, as indicated below, and you will also lose one point for each
missing family (for example, if you only turn in 9 families, you will lose one additional point). You
will also need to submit a list of the specimens submitted. Specimens will be returned, together with a
copy of the list, once they are graded. Any misidentifications can be corrected for use when the entire
collection is submitted at the end of the semester. Other specimens from the preview collection should
also be resubmitted at that time, properly arranged within the collection. If you do not turn in a
preview collection on or before the day it is due, you will lose 20 points.


Ways to Gain Points:

       These are simple:

               1.5 points for each correctly identified order
               1 point for each correctly identified family

               (Note that the first family in each order is worth 2.5 total points.)

       Extra Credit points (see extra credit handout)

               1 point for each extra credit specimen on the List of Extra Credit Families; for each
               family, you can turn in up to 5 specimens, so there’s a lot of opportunity here!
Ways to Lose Points:

      Misidentifications:

             Minus 2 points for each incorrect order
             Minus 1 point for each misidentified family

      Other potential deductions:

             Mounting Technique ..............................................................up to 15 points
             (includes pinning, point-mounting, wing-spreading, specimen orientation)

             Labeling .................................................................................up to 15 points
             (correct font, label orientation, trimming, label content)

             Condition of specimens..........................................................up to 10 points
             (specimens should be clean and free of breakage)

             Neatness and presentation.....................................................up to 5 points
             (organization and labeling of families, collection list)
