Battle of the Oleander Caterpillars

Oleander Caterpillars are typically found on Oleander trees in the semi-tropical regions of the the United States as well as further south throughout the Caribbean islands. The “Oleander caterpillars” are specially adapted to be able to eat the leaves of the normally toxic oleander tree. In fact, the caterpillars themselves can cause an allergic reaction if handled with bare hands.

Why they would fight over a small territory in a very large and mostly unoccupied tree is difficult to fathom. Nonetheless, they fought for over six hours.

This animation compares the global and regional trends in temperature anomalies as the global temperature increases overall. The equatorial and global temperature increases are roughly comparable but the southern hemisphere increases far more slowly than the northern hemisphere. This is because the southern hemisphere is mostly ocean which warms far more slowly than the land which predominates in the north.

The starting temperature is compared to the pre-industrial period before large emissions of greenhouse gases had begun.
