Question of the Week: Mayflies

Last week the question was:  What are the bugs all over the side of this dock?

These are mayflies.  Mayflies spend the majority of their lives in the water as nymphs feeding on algae and organic matter.  After 1-2 years they pupate into adulthood and leave the water to mate.  Adults lack mouth parts and well developed digestive systems, so they have only a day or two to mate and lay eggs before running out of energy.

 

Here is this week’s question:  What happened to these soybeans?
