The radiation of flowering plants in the mid-Cretaceous transformed landscapes
and is widely believed to have fuelled the radiations of major groups of
phytophagous insects. An excellent group to test this assertion is the scale
insects (Coccomorpha: Hemiptera), with some 8,000 described Recent species and
probably the most diverse fossil record of any phytophagous insect group
preserved in amber. We used here a total-evidence approach (by tip-dating)
employing 174 morphological characters of 73 Recent and 43 fossil taxa (48
families) and DNA sequences of three gene regions, to obtain divergence time
estimates and compare the chronology of the most diverse lineage of scale
insects, the neococcoid families, with the timing of the main angiosperm
radiation. An estimated origin of the Coccomorpha occurred at the beginning of
the Triassic, about 245?Ma [228-273], and of the neococcoids 60 million years
later [210-165?Ma]. A total-evidence approach allows the integration of extinct
scale insects into a phylogenetic framework, resulting in slightly younger median
estimates than analyses using Recent taxa, calibrated with fossil ages only. From
these estimates, we hypothesise that most major lineages of coccoids shifted from
gymnosperms onto angiosperms when the latter became diverse and abundant in the
mid- to Late Cretaceous.
