Common asparagus beetle
Crioceris asparagi
Size: 1/4 inch long

Where/When: Feeds on asparagus spears and ferns. Emerges in spring with the appearance of asparagus, is active until mid-June and then from late June through August.

Significance: Small numbers are usually not injurious. Larger numbers can brown asparagus spears, distort growth, and make asparagus unpalatable due to eggs laid on spears. Serious defoliation can weaken plant for next season and also make it susceptible to invasion by Fusarium, a fungal pathogen.
