The Nearctic leafminer of black walnut Coptodisca juglandiella (Chambers, 1874) was found in Hungary and reported as new for Europe. Larvae were found in leafmines on black walnut (Juglans nigra (L.)), white walnut (J. cinerea (L.)) and Arizona walnut (J. major (Torr.)); the latter two Juglans species are new host plant records for C. juglandiella. Mines of Coptodisca lucifluella (Clemens, 1860), another Nearctic invader, were found on leaves of bitternut hickory (Carya cordiformis (Wangenh.) K…

Splitting the leafmining shield-bearer moth genus Antispila Hübner (Lepidoptera, Heliozelidae): North American species with reduced venation placed in Aspilanta new genus, with a review of heliozelid morphology
Abstract The new genus Aspilantagen. n. is described to harbour Nearctic heliozelid moths with reduced venation, previously placed in Antispila Hübner, 1825, with type species Antispila oinophylla
Antispilina ludwigi Hering, 1941 (Lepidoptera, Heliozelidae) a rare but overlooked European leaf miner of Bistorta officinalis (Polygonaceae): new records, redescription, biology and conservation
It is expected that despite the new findings, this species is also declining and should preferably be monitored together with host specialist butterflies, such as Boloria eunomia and Lycaena helle.


First record of a walnut shield bearer Coptodisca (Lepidoptera: Heliozelidae) in Europe
A leafminer of the Nearctic genus Coptodisca Walsingham (Lepidoptera: Heliozelidae), a species of potential economic interest, is reported for the first time from Europe, infesting the black (Juglans
Characterization, distribution, biology and impact on Italian walnut orchards of the invasive North-American leafminer Coptodisca lucifluella (Lepidoptera: Heliozelidae).
The leafminer Coptodisca sp. (Lepidoptera: Heliozelidae), recently recorded for the first time in Europe on Italian black and common walnut trees, is shown to be the North-American Coptodisca
A new leafminer on grapevine and Rhoicissus (Vitaceae) in South Africa within an expanded generic concept of Holocacista (Insecta, Lepidoptera, Heliozelidae)
Abstract A grapevine leafminer found recently in table grape orchards and vineyards in the Paarl region (Western Cape, South Africa) is described as Holocacista capensis sp. n. It has also been found
Two European Cornus L. feeding leafmining moths, Antispila petryi Martini, 1899, sp. rev. and A. treitschkiella (Fischer von Röslerstamm, 1843) (Lepidoptera, Heliozelidae): an unjustified synonymy and overlooked range expansion
The increase in abundance of A. treitschkiella in the Netherlands since the early 1990s and in Great Britain in recent years must be regarded as part of a recent expansion into north-western Europe, whereas the native A. petryi is hardly expanding and less abundant.
Antispila oinophylla new species (Lepidoptera, Heliozelidae), a new North American grapevine leafminer invading Italian vineyards: taxonomy, DNA barcodes and life cycle
Wing pattern, genitalia, and DNA barcode data all confirm the conspecificity of native North American populations and Italian populations, and preliminary phylogenetic analyses suggest that Antispila is paraphyletic.
Distribution and Management of Black Walnut (Juglans nigra L.) in Croatia
Black walnut (Juglans nigra L.) was introduced in forest management around 1890 in the lowland regions of eastern Croatia to establish plantations on the sites too dry for the most valuable native
