2025 Caterpillar Season – Humped Oakworm

2025 Caterpillar Season, insects, Lepidoptera, macro, WGNSS Field Trips, wildlife, wildlife photography

Humped Oakworm Moth
Symmerista sp. fam. Notodontidae
Host plant(s): Found on oak (Quercus sp.)
Date(s) and location(s): 18 September, 2025 – Council Bluff Lake, Iron County, MO; 27-September, 2025 – Caney Mountain Conservation Area, Ozark County, MO
Notes: Caterpillars of S. canicosta (red-humped oakworm) and S. albifrons (white-headed prominent) are indistinguishable as larvae and are so similar as adults that the only way to distinguish the two is by dissecting the genitalia. Both species are found in Missouri and both feed on the same host plants – beech, chestnut and oaks (any members of the Fagaceae).

Question Mark
Polygonia interrogationis fam. Nymphalidae (Hodges#4420)
Host plant: NA
Date found: 16, Aug, 2025
Location found: Council Bluff Lake, Iron County, MO
Notes: Two individuals found at this date and location. One was found on sassafras and the other on redbud. Typical hostplants include elm and hackberry. One individual pupated in contained overnight, further suggesting that both were pre-pupal and collected on plants during wandering. This was found during the WGNSS joint Entomology and Nature Photography Groups’ outing to Council Bluff Lake.

Pandora Sphinx
Eumorpha pandorus fam. Sphingidae (Hodges#7859)
Host plant: Virginia creeper (Parthenocissus quinquefolia)
Date found: 16, Aug, 2025
Location found: Council Bluff Lake, Iron County, MO

Brown Panopoda
Panopoda carneicosta fam. Erebidae (Hodges#8588)
Host plant: Found on hickory (Carya sp.)
Date found: 09 & 16, Aug, 2025
Location found: BK Leach Conservation Area, Lincoln County, MO; Council Bluff Lake, Iron County, MO
Notes: With information I have, there appears to be no easy methods to discern between larvae of Panopoda carneicosta and P. rufimargo (red-lined panopoda). However, there is suppose to be distinct differences in host preferences, with P. carneicosta showing strong preferences for hickory and other members of Juglandaceae, while P. rufimardo reportedly feed on oak and beech (Fagaceae). My identification is based on the host plants on which the cats were found.
