This stem of Dogwood was split opened in late June, under the assumption that no tree crickets were going to emerge.  Lo and behold, this embryo was encountered...and proceeded to leave the egg.

Having never before witnessed the emergence of a nymph from the egg...when this tiny whitish creature was seen wriggling and writhing, it was mistaken for some type of  maggot or worm.  But as soon as it was realized that this was indeed an Oecanthinae -- photography began.























Series of photos showing a tree cricket nymph emerging from the egg.

This photo shows an embryo which failed to emerge.  Its siblings had emerged two weeks before this twig was opened.  Note the lack of development at the distal end.  It is interesting to find the dark red color on the head.  This is the color this species has as an adult (a member of the varicornis group) -- but when its siblings emerged they did not have this red color.
