Hundreds of desperate refugees from North Africa drowned this month after their overcrowded boats sank in the Mediterranean. This past weekend there was another close call. More than 700 migrants traveling in five boats were rescued off the coast of Sicily by the Italian navy and coastguard. The European Union’s border agency says about 30,000 migrants have arrived in Italy from Africa during the first nine months of this year. That’s three times higher than the migration for all 12 months of 2012.

Ecologists in Kansas and Missouri say extreme temperatures are killing a large number of butterflies and could hurt their southern migration next month.

Millions of monarch butterflies are expected to migrate south through the two states in less than a month in their seasonal trip from Canada to Mexico.

Migratory dragonflies are leaving Missouri and Illinois for areas further south. It’s part of these great travelers' annual migration pattern.

The Wandering Glider and Spot-winged dragonfly typically pass through the region in July. By early August, they are on their way out.

Bob Gillespie is a natural history biologist at the Missouri Department of Conservation. He says, up until a few year ago, scientists knew very little about how they migrate.
