Why Caterpillars Infest Your House

The army worms or tent caterpillars of May 19 had dispersed in the morning but returned to my house at night, this time to the kitchen. They crept up walls and cabinets, through the red-pepper barrier beneath the door, and squashing them left and right I thought I'd go mad, using up paper towels and tissues, finally bringing out the vacuum, harassed, disgusted. Worse than ants. There is nothing in this house for caterpillars to eat, no plants, no breadcrumbs.

But there were none in the guest room although last night they were there by the hundreds; only in the kitchen. Their doors are only a few feet apart. Why were they choosing only the kitchen this evening? (Want to see them crawl? Video, 35 seconds.)

Answer: Light. The guest room was dark tonight but the kitchen was lit. Army worms are caterpillars, soon to become moths, and moths are attracted by light. It must be that caterpillars are, also.

I shut off the kitchen light. Their numbers diminished. I doused all lights in the house but one. Their numbers diminished.

Searching the Net (briefly, because in a minute I'm going to bed and turning out all the lights) I couldn't find this conclusion anywhere else but in a book published in 1896 by the Massachusetts State Board of Agriculture. But I'm telling you: Caterpillars invading your house at night? Shut off the lights!

Won't See This Again 'til 2024

Saw several of these strange burrows ringed with cairns of mud balls, a good three inches high, this past summer. They are called "chimneys." Like nothing I'd seen before, but remarkable, very noticeable, and today I find out it's no wonder I hadn't seen them before or since, because they are the homes of the nymphs of the 13-year cicada, whose year it was in 2011. (In late May and June you couldn't take a step outdoors here without feeling them crunch beneath your feet.) Some people confuse these mounds with crayfish "chimneys," but these were located on a hill, under trees, far from any creek beds. When it rains, the cicada nymphs house-clean by pushing mud and mud balls up and out of their dwelling -- pretty good considering they haven't any arms -- and leave them right outside. Good housekeeping. Now I will know what these little mounds of mud balls are when I see them again in 2024.

My Faithfullest Friend

He's back...this time in a beautifully textured "wooden" coat and the loveliest green waistcoat -- my faithful (platonic) friend the Walking Stick. He's hanging on the porch door right now, head down, waiting for me to take his annual portrait -- much more colorful than last year's, when he dressed as a dry stick. I saw him a few days ago clad in chalk-white, playing part of the garage siding. Enter "walking stick" in my search box at upper  LEFT to see his previous outfits. Here you see him at his most handsome and tasteful.
