Zusammenfassung:	The spatial distribution of clover root curculio, Sitona hispidulus (Fabricius), eggs in relation to centers of alfalfa crowns was investigated throughout the spring oviposition period of the adults. Eggs appeared to be clustered about the crowns with approximately 65% of the total eggs sampled being found within 10 cm of the crown center. The possible influences of the egg spatial distribution on density estimates and mortality are also discussed.
