Tobacco Hornworm Week 4

Week 4


04/07/2011 --Removed hornworm from the container, currently in the pupa stage; our purpose is to document it's progression.  However, there appears to be mutation in the area of the eye and tongue case.  Upon a gentle touch with the finger the abdomen did move.  With the advisement of our professor we replaced the hornworm back into the container for a later photo and to document its survival.  We were also provided with another pupa whose form was textbook. 

Description: Aside from the mutation the pupa was brown, hard and spindle shaped.  Due to mutation there was no "handle". 

Residence: In nature pupae would be buried beneath the soil.  In the lab the pupa was kept in a dark incubator at a constant temperature of 72 degrees F, within newspaper wrapped container.
