Outline

Stigmella multispicata Rociene. & Stonis, an Asian leafminer on Siberian elm, now widespread in eastern North America (Lepidoptera, Nepticulidae)

Introduction

Topic: Increased invasive insect populations in the US

• originate from Europe and Asia

• Leaf consuming insect species 310 from Europe and 77 from Asia in 2007 (Mattson et al. 2007)
• Increased global travel/transport of goods are the cause  growing number of established alien  species (Work et al. 2005)
  • Work TT, McCullough DG, Cavey JF, Komsa R (2005) Arrival rate of nonindigenous insect species into the United States through foreign trade. Biological Invasions 7: 323–332. https://doi.org/10.1007/s10530-004-1663-x
• Not as many Lepodatra as other species (Pohl et al, 2018)
  • Pohl GR, Landry J-F, Schmidt BC, Lafontaine JD, Macaulay AD, Nieukerken EJ van, DeWaard JR, Dombroskie JJ, Klymko J, Nazari V, Stead K (2018) Annotated checklist of the moths and butterflies (Lepidoptera) of Canada and Alaska.

• DNA barcoding enabled better tracking of these porly studied groups (Landry et al. 2013)
  • Landry J-F, Nazari V, DeWaard JR, Mutanen M, Lopez-Vaamonde C, Huemer P, Hebert PDN (2013) Shared but overlooked: 30 species of Holarctic Microlepidoptera revealed by DNA barcodes and morphology. Zootaxa 3749. https://doi.org/10.11646/zootaxa.3749.1.1.​

Concluding statment: Report about insect from asia that was ID through DNA barcoding

Topic: James Vargo found UK species of Stigmella in Indiana USA

• Material sent to DNA specialist who did not recognize the moths as being native to the US
• Another specimen from Missisippi UNK

Conclusion: DNA barcoding matched these with a leafminer from Beijing China

(Final Paragraph) Redescribe S. multispicata and compare to Europian S. ulmivora  and North Americain species of Nepticulidae feeding on Ulmus.

Conclusion: Discuss probility coming from Asia to North America
