Lovebugs

Delta Journal
by Bob Thomas

Late spring ‘tis the time of year when those mysterious lovebugs are everywhere, especially spattered on the front of your car where they may clog the radiator, obscure vision or, if left too long, damage the paint with their acidic juices. Not only do they appear in great numbers in May, but lovebugs usually pop up again around September.

Leaf Miners

Nature Profile
by Bob Thomas

“Hey, look at this! It looks like a road map on a leaf!” This visitor to a typical Louisiana forest or field has just seen his first leaf miner, an insect larva which lives inside a leaf and feeds on the tissues between the upper and lower epidermis. As it moves about, a trail is produced that gives away its presence. Perfectly adapted for this lifestyle, the larvae are flattened and have reduced or no legs.

Secretive Critters Under Rocks

Delta Journal
by Bob Thomas

My first herp (reptiles and amphibians) collecting consisted of walking about searching for animals on the move. I spent many wonderful hours stalking water snakes sunning on limbs extending over the water. How many times did I get soaked and come oh, so close! As I recall, the most difficult to catch on a sunny day was the Graham’s Crawfish Snake.
