  • All specimens must have been collected during the semester but a limited amount of trading specimens between students is permitted.
  • The collection may contain both dried (e.g. pinned insects, mollusc shells) and alcohol-preserved specimens (e.g. aquatic and soft-bodied arthropods, worms, whole molluscs).
  • Collecting equipment and supplies will be available in lab or loaned to students as needed.

  • Dates and location: Thur-Sat, Mar 9-11 — La Jolla area, California
    • We will meet at Bird Rock in La Jolla on Thur, Mar 9, at noon (it is around a 6 hour drive from Phoenix, so you will need to leave early if coming directly from here!)
