Comments
. This species does not seem to be attracted by light, but was only found by sight and captured with interception traps.
Thomas (1992)
mentioned three color forms of this species: the typical metallic blue form, the orange-red,
schumacheri
form, and the reddish with large yellow spots on the dorsum,
mullenhoffi
form (
Fig. 1C
). The
schumacheri
form was not observed in
French Guiana
, unlike both the metallic dark blue and the
mullenhoffi
forms. We also observed a metallic emerald green form that we will name the
emerald
form (
Fig. 1D
). All of the ob- served blue metallic and
emerald
specimens are females and the
mullenhoffi
specimens are males. A link could exist between the color patterns of this species and the adult forms of its larval preys, even if the colors of the larvae are not the same as the adults. We observed an emerald form predating on the
Chrysomelidae
Platyphora aulica
larva, and a
mullenhoffi
form predating on the
Chrysomelidae
P. aestuans
larva. The
emerald
form has a similar color as the adults of
P. aulica
(except the head, orange in
P. aulica
). The
mullenhoffi
form arrays a similar coloration pattern (11 yellow spots, reddish background) to the adults of
P. aestuans
(8 yellow spots, red background). These resemblances may be mimetic adaptations to take advantage of similarities against predators, and perhaps also to be able to approach surreptitiously the
Platyphora
larvae preys as closely as possible since adults maternal care was observed in this genus (
Windsor
et al
., 2013
).
