Forbes ('03 — 22d Rep. State Ent. 111. — p. 8) gives a summary of what 

 is known of this species. It is a corn pest, has been found widely 

 dispersed in Illinois, and hibernates as an adult beetle. A tachinid 

 fly has been bred from the larva of S. robustus Horn. (Coquillett, 

 '97. p. 18.)

 dago (near Sta. I, a), Aug. 12 (No. 26); another specimen was 

 taken from Sullivant's milkweed, Asclepias' sullivantii (Sta. I), Aug.
