THE EFFECT OF MICRO-CAUTERIZING THE ALPPM1 ("GOLD SPOT" OF AUTHORS) OF THE PUPA OF THE MONARCH BUTTERFLY, DANAUS P. PLEXIPPUS (LEPIDOPTERA: DANAIDAE)

  • F. A. Urquhart (a1)
Abstract

By a method of micro-cauterization, in which a small area of tissue may be destroyed without bleeding, it is indicated that the pigmented areas on the pupa of the monarch butterfly, Danaus p. plexippus (Linnaeus), are involved in the distribution or formation of wing scale colouration. The paper deals with experiments involving one pair of such areas, namely the alar (Al) pigmented macula which, like the median notai macula, effects apical wing colour on the prothoracic wings.
