Info

The initial pages of this guide describe the general characteristics foridentification of the emerald ash borer. These are followed by pages showingsome additional species of Agrilus, other Buprestidae, and a few other beetlesthat have similar color and/or shape to the EAB, and which could potentiallybe confused with it.These pages can be used for basic sight comparison and possibleidentification of some of the more common species in question. This guideuses coloration differences and a few distinctive, morphological characters forcomparisons. Those using this guide should not expect to be able to identifyany given specimen with absolute certainty to the species level. There are171 species of Agrilus in North America, and only a few representatives areshown here. Many of the smaller species are very similar to each other, andmost can only be reliably identified with keys. There are a few keys for NorthAmerican Agrilus (Fisher 1928, Bright 1987, Downie & Arnett 1996 for eastern species) andother Buprestidae that can be used for identification of difficult specimens.However, it may still be necessary to send difficult specimens to an expertwith familiarity in this group of insects. There are currently no revised keysavailable to North American Agrilus or other Buprestidae that include theEAB.
An example of a species comparison to EABas used in this guide1. Scientific and common name(if available) of the speciesbeing compared to EAB.2. Side-by-side comparison ofthe species to EAB at thesame size scale.3. Text box listing size range,description of color and shape,similarities and differences toEAB, and known host plants.4. Side, top and oblique views ofthe species showing color andshape characteristics.5. Photos of the most diagnosticcharacteristics that will aid inseparation of the species fromEAB.6. Range map of the species.1 Agrilus bilineatus (Weber) 2“two-lined chestnut borer”• Length: 4.2-9.5 mm, slightly smaller than EAB.• Distinctively colored bronze-black with whiteyellowpubescent stripes extending from3edges of pronotum backwards along length ofelytra (only visible on dry specimens).• Abdominal dorsum black in color (red in EAB),pygidium with carina and projecting spine(similar to EAB).• Hosts: oaks, chestnut, American hornbeam,beech, and eastern hop hornbeam.bilineatus withcarina/spine dorsumof abdomen black5EAB withcarina/spine dorsumof abdomen redSource of morphological characteristics, host records anddistributional data primarily from Bright 1987, Downie & Arnett1996, and Fisher 1928.64
