Hi Jessica,
We are requesting Eric Eaton’s assistance with your unusual Bee.

Update: (05/28/2008)
Hi, Daniel: Sure, the bee is a male leafcutter bee in the genus Megachile. Some species have the front legs modified with feathery hairs like this, though I have no idea why. Something having to do with courtship and mating, no doubt.

Every once in awhile, the What’s That Bug? editorial staff needs to dust off the camera to get a photo just to prove we can. While gardening today, we were observing a pretty little bee we have seen in the summer in the past, but are unsure as to its identity. It flies very rapidly, and in flight, it looks pale blue. It has a striped abdomen and the ventral surface is bright yellow. There are not noticeable pollen sacs and we are wondering if the bee collects pollen on the hairs of the abdomen. If flies very quickly and erratically, and is difficult to capture photographically. After about a half an hour, our efforts were rewarded. Now we hope Eric Eaton can tell us what this beauty is.

Within minutes, Eric wrote back: “Daniel, Yes, it is a female leafcutter bee, genus Megachile, and yes, she does collect pollen in a dense brush of hairs on the underside of her abdomen. Leafcutter bees nest in pre-existing tunnels in wood (some species do make burrows in the ground). They fashion individual, barrel-shaped cells from plant cuttings. A leafcutter can shear a perfectly oval (or round) piece from a leaf in under 30 seconds! The round pieces cap the finished cell. Inside each cell she packs a ball of pollen and nectar for a single offspring. She lays an egg in the finished cell, caps it, then begins a new cell stacked atop the first, repeating this for the length of the tunnel. These are amazing insects, and vital pollinators of both wild and cultivated plants. Eric”

need help in ID’ing a bee
Sir, Today I was cleaning and working on on my RV when I saw a large bee, about the size of a bumble bee, dark green in color, carrying a leaf, fly into the tailpipe of my generator’s muffler. I waited for it to come out, but after a few minutes, it did not come out. Not wanted a clogged up muffler on my generator, I tapped on it with a hammer, still no bee. I got some wasp spray and shot a stream into the tailpipe. Nothing came out. So I decided to start the generator and see if I could blow him/her our. When I started the generator, 3 leafy, cigar shaped things flew out of the tailpipe. The are about finger width in diameter and about 3 or 3 1/2 inches long. They seem to be full of some type of yellow liquid. Attached are two photos of the cocoons or egg cases. Would really like to know what they are.
PS, I live in south Texas.

Hi Larry,
We wish you had a photo of the Leaf Cutting Bee in the family Megachilidae. The female provisions her nest with nectar and pollen and creates a series of individual cells using circular leaf fragments.
