Aphrissa orbis / Orbed
Sulphur (Poey 1832)
Collection; Mc Guire Center at the Florida Natural History Museum
Plate 19 # 2a,b p.158
This butterfly was a recent visitor to the Cayman
Recognizing females of the common
Phoebis sennae sennae
and new Aphrissa orbis Orbis
in the field is very difficult.
There is more variability with respect to hue and markings in
Phoebis sennae so that complicates the issue.
Here are some comparative observations from Dr. Jacqueline Miller
Mc Guire Center at the
Florida Museum of Natural History
where she illustrates this with their library pictures
Aphrissa orbis Female
The marking near the end of the
forewing cell is usually dark brown
and slightly cut out along
the outer margin.
Below, this end cell spot
is enlarged and more magenta
with white overscaling.
The same color combination
can be seen along the lateral or
outside margin on the forewing.
There is a reddish brown, jagged
submarginal spotband that extends
from near the FW apex and extends
about half way down the wing.
Basic color below is clear in color.
Brown border along lateral margin
of HW very reduced.
Phoebis senna senna Female
Female above, marking at the end of
the cell is circular with usually an open
circle (white or off white) in center.
Marking at end of cell becomes double spots,
silver in center and outlined in reddish brown.
A reddish brown submarginal spotband which
extends nearly to the anal or near the posterior margin
of the wing.
Basic color below is usually "peppered"
with red to reddish-brown to brown scales.
Brown border of HW more complete;
FW above border along the lateral margin crescent shaped.
