Demise

 

Stop, sit, look is a mantra that serves me well.

I was huddled near the end of a rotting log when I spotted a brightly patterned bug just a few inches away. This was quickly followed by a good-grief-what-the-heck? moment when I realized it was “attached” to a large caterpillar. What followed next was fascinating.

The piercing mouthparts of this immature stink bug had seized hold of one of the caterpillar’s hind “legs” (known as prolegs to bugsters) and it was feeding on the still-living larva.

The caterpillar was strong. It pulled that stink bug several inches across the log face. Despite its best efforts, however, it couldn’t break free.

The stink bug’s grip was stronger. In fact, several times the caterpillar swung loose, dangling in air. The stink bug never lost its hold on the log or the larva.

Although the larva was still alive when I left, the end was inevitable — it was lunch on legs for this young spined soldier bug.

The spined soldier bug goes through 5 stages (instars, for the biologically inclined) between egg and adult. Each stage looks quite different than the others. Turns out I found the third instar.

If you’d like to see its life cycle in photos, check out this link at the University of Florida.

    1. Kathy, thanks for your note and kind words. (“Mantra”contains “rant” … which is what I think I actually do 🙂 … ) The world is as it is … yet still wonder-filled. Witnessing the darker parts reminds me how precious life is, no matter how brief.

    1. Yes, sometimes that’s my reaction too. But who to root for? The bug or the caterpillar? Each is living its own life, each must eat. Should we kill wolves because they kill elk? (Hunters pay good money for hunting licenses to shoot elk.) Do we round up wild horses because they eat the forage that cattlemen lease so they can graze their cows? (Who does more damage to the waterways, horses or cattle?) We continue to struggle with such questions and not always successfully. But asking them anyways is still important. Thanks for reminding us of this conundrum.
