Assassin Bugs Hatch and Harvester Emerges

A few weeks ago I mentioned seeing an assassin bug on an alder in the Wetlands. This past Saturday (9/14) I spotted an egg case close by. The egg case is a dead ringer for that of Zelus luridus, the assassin which was spotted earlier. A close look at the mass of eggs revealed that they had already hatched. There was no sign of the hatchlings, they must have already disbursed in search of prey. I took several photos of theRead more

Harvesters Eclose

The subjects of the two images at right are what greeted me as I anxiously inspected the alder this morning. I’d been out of the “office” for three days and was hoping to find both Harvester pupae intact. The first chrysalis was indeed intact, but much darkened from when I last saw it several days ago. The darkening of the chrysalis is a sure sign that the butterfly within is soon to emerge. It’s actually transparent and what you seeRead more

The Harvester

Just a few weeks ago I posted about woolly aphids on the Hazel Alder here in our Wetlands. In that post I mentioned the possibility of Harvesters, the only North American carnivorous butterfly, making an appearance. Well, they have arrived…at least in caterpillar form. Of course, for the caterpillars to be here there had to have been a butterfly present at some point to lay eggs. It must have done its egg laying while I was making the rounds, becauseRead more

A Cosmopolitan Dragonfly

I stopped by the Sail Boat Pond, as I often do on my routine hikes around the Outdoor Exhibits, and noticed a golden-hued dragonfly clinging to one of the bungee cords which holds in place the ABS tubing meant to keep the boats from ramming into the block wall of the pond. The dragonfly was a Wandering Glider (Pantala flavescens). As I walked around the pond I noticed dragonfly exuviae hanging from the inner wall of the pond. Circumnavigating theRead more

My, how they’ve grown!

A recent post to this Journal featured two caterpillars, one of those was the larva of a Cloudless Sulphur butterfly on Partridge Pea in Catch the Wind. On August 2, I noticed one of these large yellow sulphurs lay at least one egg on the plant. Fives days later I saw one, then two, caterpillars munching away on the plant’s flowers. It’s now August 15, and the caterpillars have grown considerably. They will probably crawl off to pupate within aRead more
