Giant Walking Stick (Megaphasma denticrus)



Giant Walking Stick (Megaphasma denticrus)

Walking sticks are primarily tropical, but several species are found in the more temperate regions of North America. One usually sees males like one above because, as is the case with many insect, males are out and about searching for females. Giant Waling Sticks are the longest insects found in NA. Female can grow up to around 7" long and are less colorful and gracile (more blunt and bulky) than males. While this critter appears very conspicuous while crawling around on the porch, he can blend in well when among twigs and leaves.

Walking sticks are generally harmless plant eaters. The "pincers" at the end of his abdomen are actually claspers for holding onto a female during mating. An exception to the harmless generalization is the Two-striped Walkingstick (Anisomorpha buprestoides) which is found in the far southeastern U. S. (mostly Florida). Members of this genus can deliver a chemical spray to the eyes that can cause corneal damage.

Yellow Passionflower (Passiflora lutea)

.
Yellow Passionflower (Passiflora lutea)
.
This little yellowish-green wildflower is only about an inch across, much less conspicuous and showy that it's cousin Passiflora incarnata. Both are vines native the the southcentral and southeastern U. S. (USDA distribution map)

Missouri Flora says P. lutea grows in low rich woods, rocky woods, slopes, thickets and along railroads.. That site mentions that it is most often seen as a small non-flowering plant, but in low, moist woods flowering plants are common. This particular plant is growing in an open and rocky area alongside our road out, hardly a low, moist woodland.



Jo gets the credit for both finding and photographing this specimen.

Black Stink Bug (Proxys punctulatus)


.
Black Stink Bug (Proxys punctulatus)
Not really a rare bug, but the first of its species I've seen around our place.  Black stink bugs are found in the southeastern U. S. and range southward into the neotropics.  Like all stink bugs, this species has a probe-like mouth and feeds on plant juices.   According to BugGuide there is "some association, perhaps, with Spiderwort".
