Dogmom- love your Bluebird pics! Really good! I'll tell you that it will be hard for bluebirds to have a successful nesting experience if you have a lot of house sparrows & house wrens nesting with you. You know by law that you are allowed to remove HOSP nests, eggs, & young. We're even allowed to dispose of HOSP because they have caused such problems for our native cavity-nesting birds. Otherwise, they'll keep bluebirds or others from nesting or throw eggs out, kill babies & kill parents if they trap them in the box. If you're not willing to keep HOSP from nesting in your yard, the only thing you can do is put up a sparrow spooker after the bluebird (or other) lays their 1st egg. Since you have HOWR too, you should put up a wren guard after 1st egg is laid. Otherwise, the others won't have a chance to nest with you. Also, the only sized opening that will keep a HOSP out is 1 & 1/8, which is the size for Chickadees. Some birds won't nest in boxes with smaller entrances. Most of the time with Chickadees, you have to start out with the standard 1 & 1/2 & put a hole reducer on after the 1st egg is laid. Then, they'll usually accept it.

Hi again, Catherine. You're right. The ones that you get at pet stores often come from China. Do you have a Wild Birds Unlimited? Their dried mealworms come from Los Angeles, but are a little more expensive. However, I have purchased ones from pet stores & my bluebirds have eaten them & been fine. There are also mealworm farms across the US that also carry dried mealworms, but you'll have to order those online. I get my live mealworms online from Rainbow Mealworms. Hope that helps! Nicole

Ok, but I was judging by the three pair of legs towards the front, the set of prolegs that I see, and what appears to be a pair of anal prolegs at the back. But, certainly, you have the advantage being able to see it in person. ( By the way, caterpillars only have three pair of 'real' legs, the rest are stubby prolegs.) Anyway, it's probably some sort of darkling beetle larvae, usually called meal worms. All are organic matter or live plant eaters. They would certainly be of no benefit in a container plant's soil, where they would be tempted by tender plant roots.

Live mealworms may also suffer from relatively slow sales since even people that feed mealworms to their pet lizards, birds, and so on probably don't buy in bulk unless they're a breeder of such critters and therefore would have a constant and possibly even a daily need for such fare. As to a reasonable size to start with? The giant size might feed a few general population birds but without some care, it seems that you'd go though a container pretty quick. The smalls look tiny and you'd probably have to ration out a few more than you'd like to make a container last any amount of time. The medium size is what I'd try if I were that interested in feeding mealworms to draw in certain species. Price is right and there are enough that your mealworm experiment could last long enough for observation of any species that are drawn in just because of that addition to whatever you've been feeding on a regular basis. Long ago, I decided that within reason, if I had to ration what relatively small amount of funds I use for feeding the wildlife that comes to my little backyard compared to the enjoyment it brings me, I'd probably just take down my feeders and quit buying raw peanuts for the blue jays and that one damn ornery (but cute) squirrel that visits daily. I fully realize that not every budget is flexible enough to do that but I figure that I'm only here on this earth for a short while so why not enjoy what impacts my life and brings joy to my eyes while I'm here. Perusing a few websites on raising your own mealworms seems to be quite popular and while it doesn't look like the initial outlay would be much, would you use enough of the little buggers to make it worthwhile even if you just counted time and what space is required? Reading over those sites does remind me of a time not that long ago when every fishing and hunting magazine in existence (and they may still have them) had ads touting raising your own bigger and better fishing worms! "Yes Friends, you too can raise enough of my extra special extra large energetic red wigglers and nightcrawlers to go fishing any time you want and you'll never run out of fish bait!!!! Get your starter pack of worms NOW and in only days you'll have more worms than you can use. Send only $19.95 to PO Box XXXX, to get started." Not... Problem is that nightcrawlers won't live south of the Mason Dixon line unless you keep them in a refrigerator and most little red wigglers are just on the borderline of being so small that you almost have to use tweezers to put them on your fish hook. Too, both types have to be kept practically n the dark to keep them happy, temperature and moisture levels have to be maintained and appropriate worm food is not as easy to manage as they would have you think. Oh wait... the subject was mealworm acquisition, not fishin' worms. It appears I have strayed off subject again. Sorry bout that.
