Cross-striped Cabbageworm– EvergestisrimosalisCommon Name: Cross-striped Cabbageworm
Latin Name: Evergestisrimosalis
Appearance:
The adult has a wingspan of around 25 mm, making it larger than the diamondback moth but smaller than the cabbage looper moth. Hindwings are pale with a black border, and forewings are straw-coloured with olive to purplish-brown markings and transverse lines.
The eggs are 1.2 mm x 0.9 mm in size and are placed in tiny clusters (3-25) beneath leaves.
Larvae grow via four instars. The final instar is 15-17 mm long and has a bluish-grey back with many transverse black stripes (thus the name “cross-striped”).
Territory:
It is found in most of the eastern United States.
Damages caused by Cross-striped Cabbageworm:
Damage to cole crops is comparable to other Lepidoptera larvae, with holes or more widespread defoliation of immature and older leaves. Larvae can also feed on the exterior of the head or burrow within the growing cabbage head. Cole crop damage is comparable to other Lepidoptera larvae, with holes or widespread defoliation of young and adult leaves.

Damage to cole crops is comparable to other Lepidoptera larvae, with holes or more widespread defoliation of immature and older leaves. Larvae can also feed on the exterior of the head or burrow within the growing cabbage head. Cole crop damage is comparable to others. Larvae can also provide on the cover of the head or burrow within the increasing head of cabbage.
Life history and Habits:
The period from egg to adult areas is 18 days under warm conditions \s(35°C) to 2 months under cool conditions (20°C). The egg hatches in 2-12 days (warm and cool temperatures, respectively), the larval stage takes 2-3 weeks, and the pupal stage takes 9-11 days. It takes 3-6 days for newly emerging adults to begin laying eggs, then depositing them for the following two weeks. Adults only survive for 20 days (as little as a week under warm conditions). This pest is prevalent in the mountains and Piedmont areas of northern Georgia but has not been spotted in the southern part of the state, most likely due to its low tolerance for extreme heat.eworm – Evergestisrimosalis
