The Larva
The larva is an eating machine. Most of the body is taken up in the ventriculus which is a blind sack, not yet connected with the proctodaeum, which becomes the rectum. Thus the larva cannot defacate but can excrete through the two malpighian tubules that have a clear pathway out to the cell.
The heart exists just under the skin on the dorsum of the larva. On the ventral aspect is the ganglia which connect to the brain. Above the ganglia is the silk gland which is used later to spin a cocoon around the pupa several times as it develops.
At the back of the body, in the area that will become the abdomen, the ovaries are already prominent in the female larva. Also, already formed, is the respiratory system of spiracles and trachea.
