Eastern tailed-blue
Cupido comyntas (Godart, 1824) P-no. 77a0638, fam. Lycaenidae
Host plant: Found on wild indigo (Baptisia sp.)
Dates found: 20 June, 2026
Locations found: Victoria Glade Conservation Area, Jefferson County, MO
Notes: A tiny, beautiful, and common butterfly that is often seen in suburban backyards, the eastern tailed-blue (ETB for short) is not a caterpillar that I have had luck in finding. Finally, on an outing with the WGNSS’ Nature Photography Group in June, I found one of these on a wild indigo plant within the glade. I never expected a lycaenid caterpillar to be such a challenging photo subject. This guy was healthy and mobile, rarely settling down to get the desired photo.

2026 Caterpillar Season – Juniper Hairstreak

Juniper Hairstreak
Callophrys gryneus (Hübner, 1809) P-no. 77a0507, fam. Lycaenidae
Host plant: eastern red cedar (Juniperus virginiana)
Dates found: 9, 24 May, 2026
Locations found: Tyson Research Center, St. Louis County, MO
Notes: A master of camouflage. As the photos show, it would be a waste of time hunting for this species by eye amongst the countless branches of an eastern red cedar. Instead, using beating techniques or UV light at night are the best methods for finding these guys.

Banded Hairstreak
Satyrium calanus fam. Lycaenidae
Host plant: hickory (Carya sp.)
Dates found: 2 May, 2026
Locations found: Tyson Research Center, St. Louis County, MO
Notes: This was an interesting find. I looked through a number of fresh leaf-roll shelters, finding all of them occupied by a to be identified noctuid caterpillar. In one of these I also found this banded hairstreak caterpillar that was being attended by ants.
