Spring 2012 Bulletin of the Oregon Entomological Society Spring 2012 Bulletin of the Oregon Entomological Society Owlflies in Oregon (Neuroptera: Ascalaphidae) Ron Lyons and Dana Ross On 12 August 2004, Dana Ross collected an adult owlfly (Figure 1) in Jackson County in Oregon Gulch, CSNM, 4075´ elevation, at a black light trap. There are no additional owlfly specimens from Oregon in the collection at the Oregon Department of Agriculture (ODAC) in Salem or among the pinned specimens in the Oregon State Arthropod Collection (OSAC) in Corvallis. There is, however, another owlfly specimen from Oregon in the collection at Southern Oregon University (SOU) in Ashland. This adult (Figure 2) was collected in Josephine County, 5 miles SE of Selma on VIII-3- 85 by M.D. Coffey. Both specimens were identified from photographs as Ululodes mexicanus (McLachlan) by Joshua Jones, a Ph.D. candidate in the Department of Figure 1. Oregon Gulch Specimen (deposited at OSAC).

  • A New Type of Neuropteran Larva from Burmese Amber
    A 100-million-year old slim insectan predator with massive venom-injecting stylets – a new type of neuropteran larva from Burmese amber Joachim T. haug, PaTrick müller & carolin haug Lacewings (Neuroptera) have highly specialised larval stages. These are predators with mouthparts modified into venom­injecting stylets. These stylets can take various forms, especially in relation to their body. Especially large stylets are known in larva of the neuropteran ingroups Osmylidae (giant lacewings or lance lacewings) and Sisyridae (spongilla flies). Here the stylets are straight, the bodies are rather slender. In the better known larvae of Myrmeleontidae (ant lions) and their relatives (e.g. owlflies, Ascalaphidae) stylets are curved and bear numerous prominent teeth. Here the stylets can also reach large sizes; the body and especially the head are relatively broad. We here describe a new type of larva from Burmese amber (100 million years old) with very prominent curved stylets, yet body and head are rather slender. Such a combination is unknown in the modern fauna. We provide a comparison with other fossil neuropteran larvae that show some similarities with the new larva. The new larva is unique in processing distinct protrusions on the trunk segments. Also the ratio of the length of the stylets vs. the width of the head is the highest ratio among all neuropteran larvae with curved stylets and reaches values only found in larvae with straight mandibles. We discuss possible phylogenetic systematic interpretations of the new larva and aspects of the diversity of neuropteran larvae in the Cretaceous. • Key words: Neuroptera, Myrmeleontiformia, extreme morphologies, palaeo­ evo­devo, fossilised ontogeny.

The counties and/or cities in the state from which each species is known are listed, with full data provided when there are very few collections. Detailed range maps are provided for most species and the Virginia flight season of each species is reported. In the Neuroptera, nine families, 35 genera, and 71 species are recorded from Virginia.

In the Megaloptera, two families, six genera, and 18 species are listed. Two of these species are new state records: Neohermes matheri and Protosialis glabella.

PJ: [email protected]; KKV: [email protected] Received on 30 April 2012. Accepted on 17 July 2012. Final version received on 29 October 2012. Summary Aggregations of conspecifics are ubiquitous in the biological world. In arthropods, such aggregations are generated and regulated through complex interactions of chemical and mechanical as well as abiotic and biotic factors. Aggregations are often functionally associated with facilitation of defense, thermomodula- tion, feeding, and reproduction, amongst others. Although the iconic aggregations of locusts, fireflies, and monarch butterflies come to mind, many other groups of arthropods also aggregate. Cycloalexy is a form of circular or quasicircular aggregation found in many animals. In terrestrial arthropods, cycloalexy appears to be a form of defensive aggregation although we cannot rule out other functions, particularly thermomodulation. In insects, cycloalexic-associated behaviors may include coordinated movements, such as the adoption of seemingly threatening postures, regurgitation of presumably toxic compounds, as well as biting movements. These behaviors appear to be associated with attempts to repel objects perceived to be threatening, such as potential predators or parasitoids.

  • A New Glimpse on Trophic Interactions of 100-Million-Year Old Lacewing Larvae
    A new glimpse on trophic interactions of 100-million-year old lacewing larvae MARIE K. HÖRNIG, CHRISTINE KIESMÜLLER, PATRICK MÜLLER, CAROLIN HAUG, and JOACHIM T. HAUG Hörnig, M.K., Kiesmüller, C., Müller, P., Haug, C., and Haug, J.T. 2020. A new glimpse on trophic interactions of 100-million-year old lacewing larvae. Acta Palaeontologica Polonica 65 (4): 777–786. Larvae of lacewings (Neuroptera) are known to be fierce predators. According to the morphology of fossil forms this seems to have been the case already in the Early Cretaceous. While being predators, lacewing larvae are also food items for other organisms. Here we report two pieces of amber from Myanmar providing instances of such cases. In one amber piece several isolated stylets of lacewing larvae are preserved closely associated together. The most likely interpretation is that a predator preying on lacewing larvae has regurgitated or defecated these non-digestible pieces, yet the identity of the predator remains unclear. The other amber piece preserves a larva resembling modern day larvae of split-footed lacewings (Nymphidae). The larva has projections on its trunk, allowing it to wear a camouflaging cloak. In the head region, a mite (Acari) is attached to the larva; more precisely, the entire anterior body region of the mite is apparently inserted into the lacewing larva. The mite is smaller than the larva. It is known from the modern fauna that stage 1 larvae of Ascalaphidae can be attacked also by rather small predators, such as ants. The mite can therefore well be interpreted as a true predator instead of a parasite, especially considering the unusual mode of attachment.

The fossil record includes many psychopsidlike taxa from the Late Triassic to Early Oligocene from all major continents. Extant species have a disjunct, tripartite distribution comprising Afrotropical, south-east Asian and Australian regions that is significant to historical biogeography. Two subfamilies are currently recognized: Zygophlebiinae in the Afrotropics, and Psychopsinae in Australia and south-east Asia. This study explores phylogeny and historical biogeography of Psychopsidae, using data from biogeography, comparative morphology and molecular sequences (16S, 18S, CAD, COI). Our results show that (1) the morphological phylogeny is incongruent with molecular data, (2) Afrotropical Silveira Navás, represent a separate lineage that warrants placement in its own subfamily, (3) the family originated in Pangea, and (4) the present genus level distribution resulted from two vicariance events associated with Gondwanan fragmentation.

Large lateral eyes, ocelli present or absent; antennae long and multi-articulate, usually filiform or moniliform. Tarsi have five segments and cerci are absent. Mesothorax and metathorax similar in structure, with four subequal membranous wings that usually have a great many crossveins and extra branches of the longitudinal veins. There are generally a number of crossveins (Fig. 1) along the costal border of the wing, between the C and Sc. The radial sector often bears a number of parallel branches. The front and hind wings in North America species are similar in shape and venation and are usually held roof-like over the body at rest. 1 University of Florida Entomology and Nematology - ENY 6166 Insect Classification Summer 2009 -For Dr. P. M. Choate, By: Gloria Trujillo Fig. 1.( showing numerous crossveins) Larvae with clearly defined head capsule; mandibles and maxillae usually elongate, slender, modified for sucking; thoracic segments with walking legs with 1-segmented tarsus usually bearing 2 claws; abdomen frequently bearing adhesive disks on last 2 segments, without cerci.
