Many insects that feed on Missouri oak trees could be threatened by climate change, according to a study from the University of Missouri-St. Louis. 

Researchers from UMSL and several other universities looked at more than 250 insect species in Missouri, including leaf-tying caterpillars. Biologists reported in the journal Frontiers that the insects’ populations took major hits after mid-spring frosts and summer droughts, decreasing as much as 95% for some species.
