Roach nectarivory, gymnosperm and earliest flower pollination evidence from Cretaceous ambers

The evidence for early cockroach pollination is now substantial and unique is the forewing surface of L. vegrandis with photonic crystal structures within the scales.

Gnetum and Nymphaeaceans as Models for a Scenario of the Origin of Morphotype of Flowering Plants

A morphological analysis of the available data shows that the true angiosperm ancestor must have differed from Gnetum in some important respects, e.g., it must have had a more primitive xylem and bisexual fructifications.

First long-proboscid flies (Diptera: Zhangsolvidae) from the Lower Cretaceous of South Korea

Khramov, A.V., Nam, G.-S. & Vasilenko, D.V. 13 December 2019. First long-proboscid flies (Diptera: Zhangsolvidae) from the Lower Cretaceous of South Korea. Alcheringa 44, 160–168. ISSN 0311-5518

Evolutionary and Ecological Considerations on Nectar-Mediated Tripartite Interactions in Angiosperms and Their Relevance in the Mediterranean Basin

This hypothesis embeds recent discoveries in nectar biology, such as the involvement of nectar microbiota and nectar secondary metabolites in shaping interactions with pollinators, and it suggests a complex, multifaceted ecological and evolutionary scenario that is just beginning to discover.

Earliest behavioral mimicry and possible food begging in a Mesozoic alienopterid pollinator

Morphological insect-insect mimicry is known from few Cretaceous cockroaches and a beetle. Formicamendax vrsanskyi gen. et sp. n. (Blattaria, Alienopteridae) shows myrmecomorph features such as an

The Khasurty Fossil Insect Lagerstätte

In terms of the composition of the fauna and flora, the Khasurty locality is very peculiar, it includes both Jurassic and Cretaceous taxa, but in general it can be attributed to the Jehol biota.



Long-Proboscid Flies as Pollinators of Cretaceous Gymnosperms

The Pollination of Mid Mesozoic Seed Plants and the Early History of Long-proboscid Insects1,2,3

Evidence for pollination includes the entomophilous structure and size of pollen found on insect and plant contact surfaces and in insect guts, nutritional levels of modern pollination drop fluids similar to angiosperm nectar for supporting metabolically high activity levels of aerially active insects, and plant-host outcrossing.

A Probable Pollination Mode Before Angiosperms: Eurasian, Long-Proboscid Scorpionflies

The presence of scorpionfly taxa suggests that siphonate proboscides fed on gymnosperm pollination drops and likely engaged in pollination mutualisms with gymnosperms during the mid-Mesozoic, long before the similar and independent coevolution of nectar-feeding flies, moths, and beetles on angiosperms.

Evolution of extreme proboscis lengths in Neotropical Hesperiidae (Lepidoptera)

The range of variation that occurs in scaling relationships between proboscis length and body size is surveyed against a phylogenetic background among Costa Rican Hesperiidae and it is concluded that the evolution of extremely long proboscides results from allometric scaling with body size, as demonstrated in hawk moths.

Pollination drops, pollen, and insect pollination of Mesozoic gymnosperms

Recent focus on plant-insect associations during the angiosperm radiation from the last 30 million years of the Early Cretaceous has inadvertently de-emphasized a similar but earlier diversification

Adaptations for nectar-feeding in the mouthparts of long-proboscid flies (Nemestrinidae: Prosoeca).

The morphology of the extremely long and slender mouthparts of Nemestrinidae is examined for the first time to provide insights into adaptations to nectar-feeding from long-tubed flowers.

Pollination of sevenPlectranthus spp. (Lamiaceae) in southern Natal, South Africa

This study on the pollination of seven species of varying corolla-tube lengths shows a correlation between floral tube length and proboscis length of insect visitors, many of which are recorded for the first time as pollinators of Plectranthus.

A new long-proboscid genus of Pseudopolycentropodidae (Mecoptera) from the Middle Jurassic of China and its plant-host specializations

A new genus and species of Mecoptera with siphonate mouthparts, Sinopolycentropus rasnitsyni gen. et sp.
