A fabulously early robber for Florida. Gets the rest of the south's hopes up. This is a Laphria that is close to Laphria macquarti which was almost described by Bromley. I don't know how you separate it from macquarti unless the entire Florida population was separate. Apparently Bromley died before he could get the description finished. Note the yellow mystax and the characteristic (for this species pair) yellow hair on outer mid-tibia only. Wonderful shot from Eric. |

These are not quite as large as the above species (or the two giants lata and grossa which may be forms of the same species -- see that page). This is the true Laphria macquarti and note the mid-tibial line of yellow hair which distinguishes it from this angle. The above Florida species has the same line of yellow. |

The mid-tibial hair is also visible here and you can see the hairs in front of the halteres are dark and that the mystax and beard are black in the lower portion. Also note that the prominent hair lateral to the eyes is black in the females of this species and yellow in the lata/grossa pair. |

Side view of another female from Pope county. I never noticed until I took the below male shot that the other sexual difference is the hair lateral to the eyes is black in the female and yellow in the grand males. |

The magnificent male. They seem to love these beetles in the scarab family. Note the prominent yellow on the forelegs which the female does not have and the great suborbital yellow tufts. |

Another angle on this remarkable predator-prey pairing. L. macquarti consistently seem to take larger prey than the more massive Laphria grossa/lata combo. |

A Laphria macquarti from Texas. Unless there is an undefined species there. Remember Bullington has quite a few large Laphria species he found while doing his dissertation that have not been described. Compare with the above male. Note how this is much darker in the beard and mystax than our males. And our males have an impressive amount of yellow on the foretibia. These have almost none. And this has the black facial hair lateral to the orbits of our females. Odd. |
