We observed five larvae of Hyphilaria Thasus in their third and last stage, feeding on the leaves of a
hybrid of the orchid Dendrobium sp. The larvae were found in the Villas of Arraijan, West Panama.
The researcher extracted the five larvae from the orchid Dendrobium sp. and took them to the
laboratory. They were kept in a fine fabric mesh cage in room temperature and fed with the orchid's
leaves to continue their development. After three days, the five larvae pupated. However, after three
days, we noticed a fly larva of the parasitoid Lespesia archippivora (Riley) (Diptera: Tachinidae)
emerged from H. thasus butterfly and hid immediately under the sand bed in the cage. The Lespesia
archippivora (Riley) (Diptera: Tachinidae) fully developed after 17 days of leaving the body of the H.
thasus butterfly. Also, four adults of the H. thasus butterfly emerged after 16 days from their pupa
stage.
