Diverse organisms protect and camouflage themselves using varied materials from their environment. This adaptation and associated behaviours (debris-carrying) are well known in modern green lacewing larvae (Neuroptera: Chrysopidae), mostly due to the widespread use of these immature insects in pest control. However, the evolutionary history of this successful strategy and related morphological adaptations in the lineage are still far from being understood. Here we describe a novel green lacewing...

Summary Camouflage and mimicry are staples among predator-prey interactions, and evolutionary novelties in behavior, anatomy, and physiology that permit such mimesis are rife throughout the biological world [1, 2]. These specializations allow for prey to better evade capture or permit predators to more easily approach their prey, or in some cases, the mimesis can serve both purposes. Despite the importance of mimesis and camouflage in predator-avoidance or hunting strategies, the long-term histo...

The last 25 years of phylogenetic investigation into the three orders constituting the superorder Neuropterida—Raphidioptera, Megaloptera, and Neuroptera—have brought about a dramatic revision in our understanding of the evolution of lacewings, snakeflies, dobsonflies, and their diverse relatives. Phylogenetic estimations based on combined analyses of diverse data sources, ranging from adult and larval morphology to full mitochondrial genomic DNA, have begun to converge on similar patterns, many...

Abstract Beaks are innovative structures characterizing numerous tetrapod lineages, including birds, but little is known about how developmental processes influenced the macroevolution of these important structures. Here we provide evidence of ontogenetic vestigialization of alveoli in two lineages of theropod dinosaurs and show that these are transitional phenotypes in the evolution of beaks. One of the smallest known caenagnathid oviraptorosaurs and a small specimen of the Early Cretaceous bir...

Abstract The “Gres du Liban” [Sandstone of Lebanon] is the basal lithostratigraphic unit for the Cretaceous series in Lebanon. In the upper part of these siliciclastic-dominated strata we identified three discrete intervals characterized by their richness in amber with biological inclusions, mostly insects. The middle and upper intervals previously attributed to an Early Aptian (= Bedoulian) age are nowadays ascribed to the Early and Late Barremian respectively; the lower interval is Early Barre...

Abstract Most embryos of squamates use their egg tooth to facilitate hatching when their development is completed. After they are out of the shell, this tooth is shed and, in the case, of the grass snake ( Natrix natrix ), not replaced by a successor teeth. The structure of this transient tooth resembles the development and histology of the regular teeth of vertebrates. Morphological, histological and scanning electron microscopic observations indicated that the egg tooth of the grass snake has ...

Insects have evolved diverse methods of camouflage that have played an important role in their evolutionary success. Debris-carrying, a behavior of actively harvesting and carrying exogenous materials, is among the most fascinating and complex behaviors because it requires not only an ability to recognize, collect, and carry materials but also evolutionary adaptations in related morphological characteristics. However, the fossil record of such behavior is extremely scarce, and only a single Meso...

Summary Insects exhibit a wide diversity of anatomical specializations in their adult and immature stages associated with particular aspects of their biology. The order Neuroptera (lacewings, antlions, and their relatives) are a moderately diverse lineage of principally predatory animals, at least in their immature stages, as all have a modified piercing-sucking mandible-maxillary complex that allows them to drain fluids from their prey. As such, the larvae of various groups have evolved unique ...

Abstract The green lacewing, Mallada basalis (Walker) (Neuroptera: Chrysopidae), is one of the most important natural enemies used in biological control programs for forestry and agricultural pests. However, it is difficult to mass rear M. basalis instars because they are voracious cannibals. This study was conducted to determine the effect of cannibalism on the development and fecundity of M. basalis. We analyzed the developmental parameters of 3rd instars that cannibalized M. basalis eggs and ...

Larval debris-carrying, which occurs in many insect taxa, is a remarkable behavioral trait with substantial life history significance. For the Chrysopidae, information on the topic is scattered, and the habit's diversity and evolutionary history are unassessed. Here, we compile a comprehensive, annotated catalog on chrysopid debris-carrying and its associated larval morphology, and we identify emerging systematic patterns of variation, from larval nakedness to the construction of elaborate packe...

Abstract Three larval neuropterans (Insecta: Neuropterida) with straight mandibulomaxillary stylets are described from Lower Cretaceous (late Albian, ~105 Ma) Spanish amber: a third-instar beaded lacewing (Berothidae) from the Penacerrada I locality (Burgos, Spain), and two specimens from the San Just locality (Teruel, Spain), i.e., a tentative first-instar beaded lacewing and a remarkable specimen considered a berothid-like mantispoid or dilaroid (instar unknown) displaying a combination of pot...

Insects enclosed in amber can provide unique insights into the morphology, but also behavioural aspects of extinct species, due to their often exceptional preservation. This is especially true in the cases of so-called ‘frozen behaviour', were animals were caught in the fresh and viscid resin while e.g. mating, egg laying, capturing prey or in rare cases, hatching. Here, we report a group of heteropteran insect nymphs preserved together with their eggs in 15–20 million-year-old Dominican amber. ...

Neuropteran insects possess very distinct larval stages with prominent paired piercing sucking stylets and a specialised sclerite, the neck, between the head and the first thoracic segment. Some larva of Crocinae (Nemopteridae) are further specialised by possessing a very elongated neck region. The fossil record has already provided a large variety of neuropteran larvae, yet so far a truly long-necked form was missing. Here we report such a fossil larva, with an elongated neck region from 100-mi...
