jatrophae’s range extends to higher latitudes in both hemispheres 
than any other congener; its more polyphagous nature may be com¬ 
pared with the similar patterns found for temperate papilionids by 
Scriber (1973). 
Immature stages 
The first reliable account of the immature stages of Anartia was 
that of Muller (1886), who described five larval instars and the pupa 
of A. amathea, and correctly identified the foodplant family as 
Acanthaceae. Earlier authors (Merian, 1705, copied by Sepp, 
1852-1855 — see Muller, 1886; Seitz, 1914) erroneously reported 
the foodplant for A. jatrophae as “Manihot,” and figured adult 
butterflies together with a pubescent moth-like larva lacking scoli, 
and a pupal exuvium of dubious affinity. Later accounts of the 
immature stages are given for A. jatrophae by Scudder (1893), 
Dethier (1941), Klots (1951), Riley (1975) and Rawson (1976); for 
A. amathea by Riley (1975); for A. chrysopelea by Dethier (1941); 
and for A. fatima by Young and Stein (1976). Nothing is known 
concerning the immature stages of A. lytrea. 
Eggs 
The eggs (Figure 6) of A. amathea and A. fatima are yellowish 
green, 0.65 to 0.70 mm in diameter, slightly taller than wide, and 
have eleven to thirteen longitudinal wax-crested ribs which extend 
to within 15 degrees of the upper pole, which is centered on the 
micropyle. The ventral surface is flat. The ribs are perpendicular to 
and rest upon 40-50 low ridges with which the egg is banded. The 
number of vertical ribs is variable within species and even among 
the eggs of a single female (Dethier, 1941). The eggs of A. jatrophae 
are similar (Dethier, 1941; Rawson, 1976), but those of chrysopelea 
are wider than they are high (Dethier, 1941). We were unable to 
distinguish the eggs of A. amathea and A. fatima from one another. 
Larvae 
While Anartia larvae have been described by several authors, only 
Dethier (1941) used morphological terminology 5 precise enough for 
5 In their accounts of larval armature, some authors refer to setae as “hairs” or 
“spines,” and to scoli beset with numerous setae as “branched spines.” Many other 
inaccuracies are found in several published larval descriptions. Our terminology 
follows that of Peterson (1962); bilaterally arranged thoracic and abdominal 
armature units (e.g., scoli, verrucae, chalazae, setae) are described in the singular.
