Material examined:
1 ♀
from the
Galápagos Islands
: –
Santa Cruz
: Academy Bay. Deposited in
BMNH
.
Diagnosis:
The mostly hyaline white wings with dark brown patches terminally toward apex and basally, in addition to a mostly rust brown patch medially on dorsum (
Fig. 37
) will easily separate this species from the other
Galápagos
Spilomelinae. The forewing length of the single, unspread
Galápagos
specimen known is
12.5 mm
(wingspan about
26 mm
), but the species varies in this respect between 8 and
13 mm
(see
Hayden
et al.
, 2013
).
Biology:
Known as the Tomato fruit borer, the larva of this species has been recorded to feed on a number of
Solanaceae
species, but especially in the genus
Solanum
(
Hayden
et al
., 2013
)
. Eggs are preferentially laid on young fruits,
1-3 cm
in diameter. Newly hatched larvae immediately start boring into the fruit. Larvae consume seeds and fruit flesh and after five moults exit the fruit to pupate in a rolled leaf edge or among plant debris on the ground (
Hayden
et al
., 2013
). The only specimen recorded from the
Galápagos
was collected in the littoral or arid zone in
August 1969
.
Distribution:
Based on BMNH specimens (perhaps not all correctly identified), this native
Western
Hemisphere denizen of the tropical and subtropical regions is found in
Trinidad
,
Mexico
,
Guatemala
,
British Guiana
,
Surinam
,
Colombia
, and
Brazil
.
Hayden
et al
. (2013)
report a wide distribution from
Mexico
through the Antilles,
Central
and South America to
Peru
and
Argentina
. It is reported from
Florida
,
USA
according to
Heppner (2003)
, but it is not present in North America according to
Hayden
et al
. (2013)
. Only one specimen, collected on
Santa Cruz
, is known so far from the
Galápagos
. Academy Bay is where Puerto Ayora is located. This is the touristic hub and most populated area of the archipelago.
Neoleucinodes elegantalis
likely still occurs there in gardens.
Remarks:
The single known
Galápagos
specimen was determined with
Capps (1948)
and
Hayden
et al.
(2013)
. The female
holotype
from
Brazil
was not examined. There are other, similar species of this genus on continental South and
Central
America.
