Caterpillars walking single file

For social caterpillars, spinning down is typically a last resort since this could result in their permanent separation from the colony.

The caterpillars may have had a composite silk pathway laid along the length of a branch and were walking along it when somehow the pathway was separated from the branch and the caterpillars along with it. It is not difficult to do this if the stand is grasped and pulled from the substrate… the silk is remarkably strong. If, alternatively, the caterpillars were harassed and attempted to escape by spinning down, there would be many, separated down-stands with individuals at the ends of them.

However, it might be that the caterpillars were tightly aggregated when they were harassed so that their multiple down-strands spun in close proximity to each other, became entangled as the agitated caterpillars jostled about each other in trying to regain the tree. A bird, a person, a strong wind? According to Dr. Fitzgerald, this is not typical hickory tussock moth behavior. It may have been a fluke. More Information: When we think of social behavior in insects, what usually comes to mind are ants, bees, and termites, but there are many moths and butterflies that exhibit social behavior like this, where the larvae caterpillars live as groups and behave collectively.

There are benefits and costs to such behavior. Some of the benefits are thermoregulation see below , protection from predators, and greater efficiency of foraging. Costs include competition for food and the potential for contagious disease. In terms of foraging, the caterpillars want to eat the best food, while expending the least energy, so they can grow rapidly and prepare to metamorphose into reproductive adult moths.

Towards that end, there are three types of social foragers among caterpillars:. Warning: Do Not Eat: In my research on Lophocampa caryae I came across medical papers describing the fact that these caterpillars, like many others, have barbed defensive spines that are very difficult to remove. The hickory tussock moth caterpillar seems to be one of the most common culprits. One study described exposures over the course of two summers at the Pittsburg Poison Center.

And a doctor described a very unhappy baby who was brought to the emergency room after putting a tussock moth caterpillar in her mouth. Before you buy This video has some restrictions which may inhibit your use - please contact licensing newsflare.

Check it out. A giant green caterpillar eating a leaf. It looks like it is never going to end as its legs just keep coming! All that they had to do to avoid death was to stop the senseless circling of the flowerpot and head directly toward the food that was less than six inches away from those ever-circling crawlers.

We need direction, too! Will they not both fall into the ditch? So many people wander around aimlessly, wondering about the purpose of life.
