DRYAS IULIA´S EGG AS SEE IN THE SCANNING ELECTRON MICROSCOPY
An Egg of Dryas iulia alcionea (Cramer, 1779).
This image was made by Scanning electron microspopy (SEM) in the UFRGS as part of research of Neotropical butterfly, Heliconiinae. The external features of egg, larva and pupa of Dryas iulia alcionea (Cramer, 1779) are described and illustrated.
The range of distribution of the butterfly Dryas iulia alcionea (Cramer, 1779) is recorded from south of United Satates of America to Uruguai and Argentina (Emsley, 1963; DeVries, 1987). These species have twelve subspecies recorded by Emsley (1963), which are slightly different based on ground wing color, size and extension of black marks on the forewings that correspond to distribution of androconian in the males.
Beebe et al. (1960) investigate the egg, larvae and pupa of D. iulia and others species of Heliconinen butterflies. Fleming (1960) investigate the first instar lavae in respect its ketotaxy and morphology. This works was conducted in Trinidad and are about Dryas iulia iulia (Fabr. 1775) (Emsley, 1963). The use of morphologic and ultramicroscopic characteristics have enormous significance in the understanding of phylogeny of this group. This is particularly true when this approach come with molecular biology (Lee et al., 1992; Brower & Egan, 1997; Penz, 1999). Even being important (this morphological traits), the morphology, mainly ultramicroscopic ones, for the majority of the species of the subfamily Heliconiinae have not studies yet.
