LRB (little round beetle) again - Scymnus - male

LRB (little round beetle) again - Scymnus - Male

August 28, 2010
Size: 2.0 mm
Only a few of these were present this weekend at the lights. Keying these would be hopeless for me. I would guess phalacridae.

Scymnus securus
2mm is at the low end of the size range for this species, but the other possibility - S. rubricaudus, which is 2mm or less - has four pale abdominal sterna. I can't find anything else in the eastern U.S. with this combination of large pale apical area on the elytra, emarginate 5th sternum, mostly-dark pronotum, and small size.

Although I can't find a specific record of this species being collected in Missouri, the locations where it has been collected range from New England and Southern Ontario to Florida and Louisiana, and if you connect the dots, Missouri is certainly within those parameters. (References: (1), (2))

Moved from Scymninae.

Scymnus, will work more on it
This is definitely genus Scymnus, subgenus Pullus, and I may be able to get it to species based on the exact color pattern of the underside (thanks so much for the ventral image, it's invaluable for Scymnini!) and the large pale apical area of the elytra. I'll work on it more and see how far I can get it!
