Ladybugs to the Rescue!

Hello world,
The Galapagos, as everyone knows, has lots of biodiversity. But because of the invasic species brought by tourism, this precious diversity has been in decline. One of the invasive species is the cottony cushion scale, which draws sap out of plants. In 2009 Mark Hoddle and his colleagues released the natural enemy of the scale onto the Galapogos, the ladybug. They went back recently to see the results. Nearly 99 percent of the invasive bug species has been eliminated from the island. There was the concern that the ladybugs would eat some of the endangered bugs of the islands, but this does not seem to be the case. I think this is a good thing, but warrants a closer look. Ladybugs could eat some of the local species into extinction.
