Figures 2-5. 2 in Metopolophium festucae cerealium (Hemiptera: Aphididae), a new addition to the aphid fauna of North America

Figures 2-5. 2) Dorsum of Metopolophium sp., probably festucae sensu stricto. This aphid was collected from a fescue lawn in Boise Idaho. Note the lack of a rudimentary patch on abdominal segments V and VI (just anterior to siphunculi), and the curved, slightly darker siphunculi, as compared with Metopolophium festucae cerealium, Fig. 3. 3) Dorsum of alate Metopolophium festucae cerealium. Note abdominal pattern, especially incomplete patch on segments V and VI (just anterior to the siphunculi). 4) Metopolophium festucae cerealium antenna of apterous form. Note that joints are not darkened. 5) Metopolophium dirhodum antenna of apterous form. Note dark joints on the antenna, especially on segments V and VI.
