Whoops, the day got away, plugged in the camera and it took longer to cruise and mark a neighbors timber than I thought. I'll get a pic up soon. Ours is one of the NRCS tunnels, worth applying for if you can. Actually the insect thing can go both ways. Aphids have found one row that is going to get pulled, drip tube set into the aisle and the soil flamed with a quick pass with the weed burner to try to get on top of them before they get out of hand. So, they are able to overwinter in there. The season extension makes these well worthwhile though. For tomatoes here, we have late blight problems many years. By being ahead of the season and then closing the tunnel at night and keeping the dew off, the spores of course land everywhere, but it is hard for them to do as much as fast without water on the plant. Out in the field you can see them turn to mush in a day or so. Ours were planted a couple of weeks ago and are under lights here in the house as are peppers, more greens, well I think there's 24 flats of stuff down there now getting ready for spring.
