The Myrmecophilous Organs Ofarhopala Madytusfruhstorfer (Lepidoptera: Lycaenidae)

The myrmecophilous organs of the larva and pupa of A. madytus are described and compared to some other lycaenid species. In keeping with other myrmecophiles, the larvae of A. madytus possess both a Newcomer's organ and tentacular organs. They also produce stridulations by rapid vibration of abdominal segments five and six. The pupae of A. madytus have a stridulatory organ which is typical of lycaenids, but also appear to possess a functional Newcomer's organ and modified tentacular organs. The importance of vibration as a previously ignored means of ant‐lycaenid communication is emphasised.
