is a recently approved biological control agent for the highly invasive Brazilian peppertree in Florida, USA. Prior to approval for field release in 2019, thrips colonies used for host specificity testing were produced and maintained in small cylinders to fit in restricted quarantine spaces. This next segment in the classical biological control pipeline is mass production and distribution of .

Dispersal ability and host plant specificity are thought to impact the history and diversity of insect populations across the sky islands. We aimed to investigate the population structure and phylogeography of two pine-feeding pierid butterflies, the pine white () and the Mexican pine white (), restricted to these "islands" at this transition zone.

Butterflies are some of the best representatives used to study mimicry, with the monarch butterfly, (Lepidoptera: Nymphalidae) a well-known model. We are the first to empirically investigate a proposed mimic of the monarch butterfly: , the Mexican pine white butterfly (Lepidoptera: Pieridae).

We investigated the role of a pine tree parasite, dwarf mistletoe (Arceuthobium spp.) M.

Organisms at their range boundaries are particularly sensitive to climate change. As predominantly terrestrial poikilotherms, insects are often geographically limited by extremes in ambient temperatures.
