Question of the Week

Last week the question was:  What is going on with these tobacco seedlings?

These seedlings are showing symptoms of chlorine damage.  The grower washed the trays with bleach and didn’t quite get it all out when the trays were rinsed off.  This caused some burn on the margins of the earliest leaves and stunting around the edges of the trays.  The plants seem to be growing out of it, though some of the more severely stunted plants may never catch up.


Here is this week’s question:  This is the pupa of a Saturniid moth.  Is it male or female?
