There is a bumblebee-sized, black and red, fuzzy legged bug that is desperate to lay eggs on my renegade pumpkins.  Whatever eggs I don't find and scrape off turn into fuzzy black and red caterpillars with a voracious appetite for pumpkins leaves.

Gah!  I finally found it on google.  It's an effin' squash borer.  Field trip to the nursery for bT tonight methinks.

Apparently those fuzzy black & red caterpillars have nothing to do with the puzzle.  They're some other pesky problem.

ETA: Does anyone know how to inject bT into squash vines?  What kind of syringe do I need?  Do I need to use a needle or just the syringe?  Should I do it above or below the squash borer hole?  Should I inject all the plants even though only one has a hole?

The caterpillar identification book at the nursery has informed me that the red & black fuzzy things are actually Giant Leopard Moths.  I've never seen them around, but obviously, I'm just not paying enough attention.
