Question of the Week: Pupa

Last week the question was:  What is this?


This is the pupa of a tobacco hornworm.  This is a rarely seen form because tobacco hornworms pupate 6-8 inches underground.  Once the worm has reached its final juvenile stage it drops off the host plant (tomato, tobacco, eggplant, etc.) and instinctively starts burrowing downward.  Tobacco hornworms can have two or more generations per year, though the hornworm pictured above has overwintered as a pupa and will emerge later in the spring.  For more info, take a look at this UF page.


Here is this week’s question:  What disease has caused this lesion that easily separates from the healthy tissue of this strawberry?
