Eastern Lubber Grasshopper - Hatch Day - Romalea microptera Baton Rouge, Bluebonnet Swamp Nature Center, East Baton Rouge Parish, Louisiana, USA April 6, 2021 Size: about 3/8 inch long
Many (most?) people here likey know the adult Eastern Lubber Grasshoppers. (over 3 inches long).
Right now, many are probably seeing the just hatched youngsters. (about 3/8’’ long).
• Yesterday (4/6/21) at Bluebonnet Swamp in Baton Rouge, LA, I ran across a small section where there were thousands of the little black colored ones.
• And a hundred or so of similar sized red ones.
o They are red for several hours after hatching, gradually turning black.
I located some groups of red ones oozing from between the stones that made the trail bed.
According to literature:
“The eggs of lubber grasshoppers are yellowish or brown in color. They are elongate elliptical in shape and measure about 9.5 mm in length and 2.5 mm in width. They are laid in neatly arranged clusters, or pods, which consist of rows of eggs positioned parallel to one another, and held together by a secretion. Normally there are 30-50 eggs in each pod.
The female deposits the pod in the soil at a depth of 3-5 cm and closes the oviposition hole with a frothy secretion or plug. The plug allows the young grasshoppers easy access to the soil surface when they hatch.”
The first two pictures show a group oozing to the surface.
• Notice that as the come the surface, they still at least partially encased and entangled in a clear membrane.
• They are wriggling and squirming to get their legs etc. free of this membrane. It gradually slips to the btm and eventually drops off their butt and they walk to greener pastures.
After a group of red ones cleared an area, I dug down until I found 2 eggs with the young still inside.
• Pictures 3 thru 8 show them wriggling their way out of the eggshells and the membranes. Usually this is occurring underground, out of sight.
Pictures 9 thru 11 are views of their empty egg shells.
Hope some have time to wade thru this.
• So far, I have not been able to locate some of these details in literature.
