Advanced Morphology Techniques Reveal Tobacco Hornworm’s Secrets

Though studied for decades as a model organism, the tobacco hornworm's lack of silk production has never been thoroughly researched, until now. A team of researchers combining high-tech microscopic imaging with genomic techniques have captured in new detail the caterpillar's first instar silk-producing anatomy and subsequent loss of that capability as it molts to later instars.

So Many Shot Hole Borers: New Research Charts Four Nearly Identical Species

Tiny beetles once known as tea shot hole borers are actually a group of four distinct species that appear almost exactly the same to even the trained eye. In a new study, researchers combine both physical measurements and molecular genetics to better define the members of the Euwallacea fornicatus cryptic species complex.
