The Katydids are a dominant summer evening and dusk event at least at my house. No animal dominates the Katydids at night in July and August in my woods. And I presume over much of the wooded south. Katys are in the superfamily Tettigonioidea. They are more closely related to crickets than grasshoppers. The antenna, unlike grasshoppers are often much longer than the body of the insect itself. Males of almost all the species produce calls by rubbing together the bases of the forewings. Their ears are on their foretibias. This list does not include the predaceous Shieldbacks.

Our eastern Katydid list for now includes:

 

Common True Katydid, Pterophylla camellifolia : Entire east except southern Florida where the Florida Katydid, Lea floridenis replaces it. There is a Truncated True Katydid, Paracyrtophyllus robustus in central and eastern Texas as well.

This is the female Common True. The only True Katy in many areas. This is the double maraca sound or triple maraca that the Katydids get their name from. It can sound like Kay-tee-did in the triple form. And the choruses can be blanketing and massive. They don't often descend from the treetops. And are not supposed to come to lights. I find the females on my porch frequently for whatever reason. In the yard, they will often walk to the nearest tree trunk as this one did and work their way back up. May 31 2012 was the first night I heard them in 2012.

If there is a more impressive leaf creation in the insect world than the True Katy wing I am not sure what it is. Another female on my front porch in July.

 

And then you find one like this. Intense red legs and red antenna. From Bell Slough and I am not sure I have seen any Pterphylla at my house with this much red veining. Either they can chameleon or their diet makes the red more intense. I presume this is a male but can't see any definitive parts.  

Known Scudderia species of the east are noted above. After thinking for a long time this was a Thread-leg, I was straightened out on bugguide and this appears to be a late female nymph of S. furcata. This one was in a cypress swamp and this species has a broad US range.

Scudderia female in my yard 2011. I grabbed her afterward and she appears to be S. curvicauda. S. curvicauda and S. furcata females are close in appearance. 

And an Amblycorypha representative. Looks like a male to me and I believe it is A. oblongifolia. Present in the whole state. Call is the zeee-dikk call.  

And while staying at a cabin in Newton county we had quite a few Lesser Anglewings, Microcentrum retrinerve, calling around us. This one showed up at dusk on the deck. Not as leafy as the Common but still impressive. The call is a quick tsst tsst tsst.  

And Norm's Orchelimum species. Obviously a fine female. We have about 6 or 7 species. This is closest to the Long-spurred Meadow, O. silvaticum which has truly one of the most pleasing songs in the Katy group to my ear.  

 

 

The carnivorous Shieldback's which are in their own subfamily Tettigoniinae are mainly a western event but there are about ten species that make it into the east (compare this to 112 in the west). This is a female Protean Shieldback, Atlanticus testaceous. Protean song. Protean BG images I thought it was a Least song. Least BG images. But Least apparently has a more curved ovipositor in the female. The American Shieldback, A. americanus  occurs very close to the eastern boundary of Arkansas. American song. American BG images.


The same species in 2013 in the yard. This female may not be fully adult.
 
The male from Bell and I presumed this was also the Protean. There was a female nearby. I think she did have a straight ovipositor. But this looks more like images of the Least Shieldback, A. monticola. Femur to pronotum and wing extensions help separate them. This looks like short wing extension to me. I remain in education mode for these.

Apparently several species of Katydid come in the fabulous pink form. This nymph may be another Scudderia or Amblycorypha.  But always a wonder to see.
