Taxonomy

Crocidosema lantana Busck (Tortricidae: Olethreutinae: Eucosmini)

Common name: lantana flower-cluster moth

Synonyms: corynetes (Epinotia), eridela (Eucosma), perversa (Eucosma), phaedropa (Eucosma), polyphaea (Eucosma), tornocosma (Eucosma)

Adult Recognition

FWLFWL:
forewing length; the distance from the base of the forewing to the apex, including fringe
: 4.0-6.0 mm

Head, thorax light brown to brown; forewing with ground color light brown to brown; ocellusocellus:
forewing pattern element - an ovoid region anterior to the tornus; adult head - a simple insect "eye" located dorsal to the compound eye
surrounded by white-gray scaling; dark brown to black triangle present anterioranterior:
before, to the front, toward the head
of ocellusocellus:
forewing pattern element - an ovoid region anterior to the tornus; adult head - a simple insect "eye" located dorsal to the compound eye
, sometimes continuing along much of inner margininner margin:
see dorsum
(this area sometimes white instead); costal strigulaecostal strigulae:
small, usually pale, semirectangular marks along the costa
short, white; male with large, well-developed costal fold; hindwing brown.

Male genitalia are characterized by a short uncusuncus:
a sclerotized process which is fused to the posterodorsal margin of tergum IX
; semicircular, free sociisocii:
a pair of lightly sclerotized setose lobes
; valvaevalva:
an appendage flanking the intromittent organ that is used to clasp the female during copulation
with a large basal excavation, saccular angle approximately 90 degrees, and a moderate cuculluscucullus:
the distal portion of the male valva
. Female genitalia are characterized by narrow papillae analespapillae anales:
the female ovipositor lobes
; a bilobed sterigmasterigma:
the sclerotized region surrounding the female ostium bursae
with small ostiumostium:
see ostium bursae
; a ring of fine sclerites around base of corpus bursaecorpus bursae:
a dilated membranous sac at the anterior end of the bursa copulatrix
; and two large, opposed, blade-like signasignum:
a sclerotized projection or patch on the interior of the corpus bursae
.

Larval Morphology

The following account is summarized from Swezey (1924).

Mature larva approximately 6 mm in length; head black; prothoracic shieldprothoracic shield:
a sclerotized plate on the dorsal surface of the prothorax
with a black spot; body brownish-gray with a slight red tinge; anal fork present; SV group on A1, 2, 7, 8, 9 usually 3:3:2:2:2.

Detailed figures of larval chaetotaxychaetotaxy:

are available in Zimmerman (1978)Zimmerman (1978):

Pupa brown, approximately 5 mm in length.

Similar Species

Crocidosema lantana is very similar to members of the Crocidosema plebejana complex. Members of this complex average larger than C. lantana and lack a costal fold but possess a larger, denser cubital pectenpecten:
a comblike or rakelike structure located on the first antennal segment
in the hindwing. In addition, the cuculluscucullus:
the distal portion of the male valva
of the male valvavalva:
an appendage flanking the intromittent organ that is used to clasp the female during copulation
of C. plebejana is very different: almost triangular in shape and with large spines near the apexapex:
the point furthest removed from the base or at the end of the costal area
. The females of C. plebejana are quite distinct as well: a simpler sterigmasterigma:
the sclerotized region surrounding the female ostium bursae
; ring of fine sclerites around base of ductus bursaeductus bursae:
a membranous tube connecting the ostium bursae to the corpus bursae
absent; and smaller signasignum:
a sclerotized projection or patch on the interior of the corpus bursae
.

Biology

Little else is known about the life cycle of C. lantana except for the following account summarized from Swezey (1924). 

Eggs are laid in the flower heads of the host plant, often Lantana, before the blossoms open. Larvae bore into the growing shoots of the host plant, but also feed in the flower heads and fruit. Adults and larvae can be found year-round in Hawaii (UHIM collectionUHIM collection:
