Pyroderces badia
was described by R.
Hodges (1962)
from a specimen from the J. K. Small collection at the USNM.
Description. Egg.
Very small size; completely silvery white and changing to snowy white before hatching.
Larva.
First instar is dark-pink, head and last abdominal segment dark-brown, thorax black with silver band in pronotum; Second to fifth instars similar to first, except color soft pink and length
5.8–8.9 mm
(
Fig. 1I
).
Pre-pupa.
Similar in size and color to that of last instar but wider and paler.
Pupa.
Elongate, similar size to last larval instar.
Adult.
Sexually dimorphic, female larger and darker than male.
Wing expanse
: males
3.4–4.7 mm
, females
4.9–5.8 mm
.
Wings.
Dorsal surface
: Forewings pale-brown with a series of transverse markings of different color shades ranging from dark-brown to white occasionally overlain with golden-brown or dark-gray scales. Hindwings dark-brown with overlaid with dark-gray or white scales.
Ventral surface
: Both wings dark-brown with overlaid with dark-gray or white scales.
Head.
Antennae
: Filiform; nearly ¾ length of the body.
Vertex
: Brown.
Mouthparts
: Labial palpi with second and third segment longer than first; lines with different shades present.
Body.
Thorax and abdomen
: Generally reddish-brown but sometimes pale-brown or brown blended with gray and dark-brown.
Legs
: Similar to labial palps in coloration (
Fig. 2E
).
Distribution.
Pyroderces badia
is found in the
USA
, mainly in
Florida
, but has also been reported in
Louisiana
,
Washington
,
California
,
Maryland
and
Hawaii
(
Hodges, 1978
;
Adamski et al. 2006
;
Bella and Mazzeo 2006
). It has also been observed in
Costa Rica
(Quesada-Jiménez 2013),
Cuba
(
Alonso et al. 2015
),
Barbados
(
Bennett and Alam, 1985
) and
Honduras
(
Miller et al. 2012
). Additionally,
P. badia
has been recorded in nine European countries:
France
,
Greece
,
Italy
,
Malta
,
Netherlands
,

,
Spain
, and the
UK

Manilkara sapota
(L.) van Royen,
new host record
and first record on
Sapotaceae
.
Natural history.
The adults are polyphagous, and feed on many species, but almost all the resources that they consume are organic remains (dead flowers). Therefore, they are not a problem to most of their hosts, but sometimes they feed on some of the healthy flowers close to the dead ones. They were observed eating both healthy and dry flowers of
M. zapota
.
The adults are usually active at night or in the twilight in
Florida
during summer (June-September). The females lay eggs inside dry or healthy flowers. When
the larvae
hatch, they start to feed on the organic remains inside the flower. The larval stage lasts about 18–21 days, but if the inserted larvae do not have enough resources, they may enter diapause. Pupation occurs inside the flower usually in a rolled sepal. The pupal stage has a duration of 23–29 days.
Damage.
The flowers infected by
P. badia
do not show external damage but turn yellowish brown until desiccated.
Management.
We observed an unidentified parasitoid (
Braconidae
) on
P. badia
. The use of
Bacillus thuringiensis
Berliner, 1915
as a biological control agent has also been reported successfully (Quesada- Jiménez 2013). Chemical control has not been investigated.
