Pest Profile Photo credit: Tom Murray, Bugguide.net Common Name: Lilac Leafminer Scientific Name: Caloptilia syringella Order and Family: Lepidoptera: Gracillariidae Size and Appearance: Length (mm) Appearance Egg -Found in between leaf layers, may appear as small raised spot on the leaf Larva/Nymph -Pale yellow or green in color 5-7mm -Dark green stomach and light yellowish brown head Adult -Bodies have some light and dark brown striping 6-7mm -At rest the moth will fold its wings tube-like over its body -Wingspan of 10-13mm -Forewings: golden brown or bray with various dark edged whitish-yellow markings -Hindwings: dark brown Pupa (if applicable -Can be found buried 1-2” in the soil Type of feeder (Chewing, sucking, etc.): Chewing Host plant/s: Lilac bushes but occasionally Ash trees. Description of Damage (larvae and adults): The lilac leafminer larvae will produce a blotch mine on the foliage and when older they will roll and tie the leaf with silk. The larvae and adults will continue to feed on the leaves from within the tied leaf. Occasionally, leafminer populations will get to damaging numbers but typically they only infest a few leaves.

Checkered Beetles Moths (Lepidoptera: Gracillariidae) – Hazardous Phytophags of Arboreal and Shrubby Plants of Botanical Gardens and Plantings of Kiev M
UDC 632.634.791.937 (477.75) © 2017 Checkered beetles moths (Lepidoptera: Gracillariidae) – hazardous phytophags of arboreal and shrubby plants of botanical gardens and plantings of Kiev M. Lisovyi, O. Sylchuk Natsional University of Life and Environmental Sciences of Ukraine, Heroev Oborony str., 13, Kyiv, 03041, Ukraine P. Chumak, V. Kovalchuk, Botanichny Garden of Acad. O. Fomina The purpose. To carry out probes on revealing and specification of species composition of checkered moths (Lepidoptera: Gracillariidae) in conditions of botanical gardens and plantings of Kiev. Methods. Standard methods of faunistic research in entomology, population ecology, and protection of plants. Results. It is determined that 24 kinds of checkered moths are eating 54 kinds of plants which are widely used for gardening in Kiev. For the first time the following kinds are revealed: Phyllonorycter issikii, Phyllonorycter platani, and Phyllonorycter emberizaepennella. At calculation of Palii-Kovnatski indexes they specified that in city plantings the dominant phytophags are Cameraria ohridella (94,11%), Phyllonorycter populifoliella (86,37%) and Gracillaria syringella (59,14%). They consider that in formation of the secondary areal of invasion kinds of checkered moths the great value has an areal of spread of the host-plant. Environmental analysis is carried out of checkered moths of family Gracillariidae which is spread in cities of the Europe and which are absent in fauna of cities of Ukraine. That has important theoretical and practical value for ecology, entomology and protection of plants against hazardous checkered moths. Conclusions. All the probed kinds of checkered moths by their trophic specialization may be distributed into polyphages (6 kinds), oligophages (14 kinds) and monophages (3 kinds).

(Lepidoptera, Gracillariidae, Gracillariinae) is described as a new species from New Zealand. It is regarded as endemic, and represents the first record of its genus from the southern hemisphere. Though diverging in some morphological features from previously de- scribed species, it is placed in genus Sabulopteryx Triberti, based on wing venation, abdominal characters, male and female genitalia and hostplant choice; this placement is supported by phylogenetic analysis based on the COI mitochondrial gene.

O. De Prins Diksmuidelaan 176, B-2600 Antwerpen (Belgium) Abstract A new Gracillariid species is described from Morocco : Gracillaria toubkalella n. sp. The lectotype of Coriscium norvegiellum Wocke, 1893 is designated and the synonymy of this taxon with Gracillaria loriolella Frey, 1881 is established. Résumé L'auteur décrit une nouvelle espèce de Gracillariidae provenant du Maroc : Gracilla- ria toubkalella n. sp. Il désigne le lectotype de Coriscium norvegiellum Wocke, 1893 et établit la synonymie de cette espèce avec Gracillaria loriolella Frey, 1881. Introduction In April 1983 I was able to breed some specimens of a Gracillariid species of which I found full grown larvae in twisted Fraxinus leaves in the garden of the Grand Hotel du Toubkal at Asni (Morocco, High Atlas). Almost immediately after their capture the larvae began to construct a pure white silken cocoon between the leaves, against the lid of the box in which they were contained or in the edges ofthat box. The first imago emerged on 20th April 1983. A total of 19 males and 20 females emerged between that date and 29th April. The specimens remained undetermined for about two years, in spite of thoroughly searching the series of Gracillariidae in the museums of Amsterdam, Brussels, Leyden and London and a heavy correspondance with several European specialists on the matter.

Evidence is presented that all British specimens of Calybites hauderi (Rebel, 1906) are not that species but the first brood of bivoltine Caloptilia semifascia (Haworth, 1828). C. hauderi is removed from the British list and its occurrence in Belgium is questioned. C. semifascia is normally univoltine in the British Isles but bivoltine populations are now spreading in southern counties. Zusammenfassung. Der Nachweis wird erbracht, daß es sich bei allen britischen Calybites hauderi (Rebel, 1906) um die erste Generation der bivoltinen Caloptilia semifascia (Haworth, 1828) handelt. C. hauderi wird von der britischen Liste gestrichen und das Vorkommen in Belgien wird angezweifelt. C. semifascia ist auf den Britischen Inseln normalerweise univoUin doch breiten sich in den südlichen Grafschaften zunehmend bivoltine Populationen aus.

(Lepidoptera: Gracillariidae: Epicephala) and Leafflower Trees (Phyllanthaceae: Phyllanthus Sensu Lato [Glochidion]) in Southeastern Polynesia
Coevolutionary Diversification of Leafflower Moths (Lepidoptera: Gracillariidae: Epicephala) and Leafflower Trees (Phyllanthaceae: Phyllanthus sensu lato [Glochidion]) in Southeastern Polynesia By David Howard Hembry A dissertation submitted in partial satisfaction of the requirements for the degree of Doctor of Philosophy in Environmental Science, Policy, and Management in the Graduate Division of the University of California, Berkeley Committee in charge: Professor Rosemary Gillespie, Chair Professor Bruce Baldwin Professor Patrick O’Grady Spring 2012 1 2 Abstract Coevolution between phylogenetically distant, yet ecologically intimate taxa is widely invoked as a major process generating and organizing biodiversity on earth. Yet for many putatively coevolving clades we lack knowledge both of their evolutionary history of diversification, and the manner in which they organize themselves into patterns of interaction. This is especially true for mutualistic associations, despite the fact that mutualisms have served as models for much coevolutionary research. In this dissertation, I examine the codiversification of an obligate, reciprocally specialized pollination mutualism between leafflower moths (Lepidoptera: Gracillariidae: Epicephala) and leafflower trees (Phyllanthaceae: Phyllanthus sensu lato [Glochidion]) on the oceanic islands of southeastern Polynesia. Leafflower moths are the sole known pollinators of five clades of leafflowers (in the genus Phyllanthus s. l., including the genera Glochidion and Breynia), and thus this interaction is considered to be obligate. Female moths actively transfer pollen from male flowers to female flowers, using a haired proboscis to transfer pollen into the recessed stigmatic surface at the end of the fused stylar column. The moths then oviposit into the flowers’ ovaries, and the larva which hatches consumes a subset, but not all, of the developing fruit’s seed set.
