BI 452. Biology of Insects: Syllabus and Course Packet Instructor: Phil Schapker: [email protected] Class Days: Monday – Thursday, 9:00 am – 1:00 pm. Overnight Field Trip: Friday, July 29 – Saturday, July 30
Course Content: This course introduces principles of insect biology with emphasis on insect diversity, life history, and behavior, especially behavior associated with communication, courtship, and social behavior. Through multiple class excursions to the field, including an overnight field trip to the H.J. Andrews Experimental Forest, students will learn valuable techniques in collecting insects and preparing museum-quality specimens for further study. By the end of the class, students will be able to identify the orders of Class Insecta and arrange them in a meaningful way according to their evolutionary relationships, and have familiarity with over 50 families of insects that are key players in a wide variety of disciplines from ecology and pest management, to theoretical biology. Students will also learn methods of observing behavior, practiced on live insects kept in the classroom. Finally, students will develop skills in writing and presenting through an independent research project. Learning resources:
1. Book: Broadsides from the Other Orders, by Sue Hubble. Random House: New York. 1993.

Instructions and Grading Rubric for Insect Family Slide - 25 points possible
I am assigned the families ___________________ and ____________________
in the order ___________________.
For each family, make two PowerPoint slides including the following:
First slide:
o In large lettering at the top of the slide, list both order and
family separated by a colon like this.. Coleoptera: Buprestidae __/2.5
o One medium- to high-resolution image of a species from that family. __/2.5
Preferably something that occurs in Oregon
Image should be no smaller than half the size of the slide. __/2.5
May be as large as whole slide.
Include the species name on slide and link to source in notes. __/2.5
o How is the family identified?
List identifying features __/2.5
Include an extra picture, if necessary, to illustrate __/2.5
important features such as wing venation
o Include some measure of diversity of the genus __/2.5
ex: “450 species in 3 subfamilies wordwide.”
ex: “15 spp. worldwide, 2 spp. in NA.”
Second slide:
o 4-6 images of species from that family demonstrating diversity __/2.5
o List names of species, and photo credits in notes section __/2.5
o Use animation to make Order: Family title appear on click __/2.5
Species names should be written in italics and preceded by the
genus. Often, the last name of the author (original describer)
and year of original description accompanies the species name.
Ex: Homo sapiens Linnaeus, 1758

Grading Rubric for Research Paper
400 level - 11 sentences as follows:
1. Introduction that explains topic with clear thesis statement.
Example: “The rapidly-evolving mitochondrial gene CO1 has gained wide appeal among insect
systematists for its potential to differentiate cryptic species; however, several conditions exist that could
violate researchers’ assumptions and make the results of mt-CO1 analysis inaccurate or misleading.”
2. First example related to 1st peer-reviewed scientific article, properly cited. “The first problem arises as a consequence of the CO1 gene typically being passed down only through the
female line, making recombination impossible and guaranteeing continuously bifurcating CO1 lineages.”
3. Extension of first example ((article is cited here, but could have been in the proceeding sentence))
“A simulation study by Irwin (2002) showed that as population sizes and average dispersal distances
decrease, it becomes increasingly likely for phylogeographic breaks to occur among matrilineal
lineages within species, even in the absence of geographic barriers to gene flow.
4. Extension of first example
“Thus, systematists only looking at CO1 might see two populations with deeply separate mt-CO1
lineages and infer a species boundary where a nuclear-coding gene would tell a different story.”
5. Second example referring to another peer-reviewed article, properly cited.
6. Extension of second example
7. Extension of second example
8. Third example referring to a third peer-reviewed article, properly cited.
9. Extension of third example
10. Extension of third example.
11. Conclusion that summarizes the paragraph.
Paragraph is followed by a section titled “Works Cited”
500 level –
Same as above, except there are 2 paragraphs, with a total of 6 articles cited.
The 1st paragraph may have an additional introductory sentence that ties both paragraphs
together.
The 11th sentence of the 1st paragraph is a transition sentence.
