A Melanic Pieris Rapae from Michigan (Lepidoptera: Pierdae)

The Arthur J. Yates collection of Michigan Lepidoptera, recently donated to Michigan State University (see Fischer, 1967), contained a striking melanic male cabbage butterfly [Pieris rapae (Linnaeus)] (Figs. 1, 2) now incorporated into the MSU series. Yates collected the specimen on 29 May 1934 in Roseville, Macomb County, near the western shore of Lake St. Clair in southeastern Michigan. An examination of the androconia and genitalia, using the characters described by Chang (1963), assured proper identification of the specimen. Although we have found no record of a similar rapae taken in North America, there are some named European forms of various species of Pieris that resemble our specimen

A Numerical Study of Non-Perturbative Unification

Non-perturbative unification provides an attractive framework for exploring physics beyond the Standard Model. It assumes nothing about the form of the unified physics, yet provides low-energy predictions of Standard Model couplings. In this investigation, we consider models that add multiplets of SU(5) to the Standard Model in order to unify in this way. We present a search for those that correctly reproduce experimental results and find that some models unify with added matter at the scale of the potential future 100 TeV collider. We conclude with an illustrative example of how these models can be built off of for further model building beyond the Standard Model with extractable phenomenological results
