Pupal case embedded in decaying rat?
June 1, 2010
Hello! I have long loved your website and need your help! This large, hive-shaped brown growth is emerging from the throat of a large brown rat my cat killed. You may be able to see the significant maggot population under the forearm, but the corpse is still intact for the most part. It appears larger than most of the fly pupae I have found descriptions of on the internet. Can you help? I am very curious – almost mistook it for a cancerous growth! Thank you!!
W. Barker, huge fan!

Dear W. Barker,
If we had just read your letter and there was no photo, we would have argued that the creature was a Rodent Botfly in the genus Cuterebra, but the thing on your dead rat looks nothing like the Rodent Botfly Larva pictured on BugGuide. We are going to post your letter and photos and request assistance from our readership.
