Two weeks prior to this photo, this female O. nigricornis was a healthy tree cricket -- slender silhouette and light green in color.  One day after this photo was taken, she expired.  Note the grossly distended abdomen.  (See photo below.)

This horsehair worm was found in the container with the female in the above photo.  It measured 4cm in length.


It is possible this strand-like object is normal anatomy for a young female tree cricket -- but based on the above photos, might it be some type of worm?



This 3.5mm long  fully-developed wasp  was found inside a twig alongside hatched and unhatched tree cricket eggs.   Several wasp species are known to parasitize tree cricket eggs.

This wasp was ID'd as parasitic Apocrita » Platygastroidea » Platygastridae » Scelioninae » Oethecoctonus » Oethecoctonus oecanthi                                        See at:  http://bugguide.net/node/view/431906#849940

Close-up view of the head and thorax of the parasatoid found in the twig with tree cricket eggs.


Although this is not a good photo, one is still able to see the limbs of a Two-spotted tree cricket instar as this Isodontia elegans wasp drags it off to its nest.

This was lit on this branch for only a few seconds and happened to land in a brightly lit spot -- therefore these photos are not ideal.  However, one can see the limbs and the underside of this N. bipunctata instar -- as well as its two hind legs dangling below the branch.
