Hi Mike,

The so-called "short-winged blister beetles" are those in the genus  
Meloe. In Nova Scotia four species occur (there are 22 species in  
North America):

Meloe angusticollis Say - In the northeast it is found in MA, ME, NB,  
NH, NS, NY, ON, PE, QC, RI, & VT. It is distributed throughout North  
America.

Meloe dianellus Pinto & Selander - In the northeast it is found in  
CT, MA, ME, NH, NS, NY, ON, QC, RI, & VT. It is distributed  
throughout North America.

Meloe impressus Kirby - In the northeast it is found in ME, NB, NH,  
NS, NY, ON, PE, QC, & RI. It is a more northern species which does  
not occur in the American southeast or southwest.

Meloe niger Kirby - In the northeast it is found in MA, NH, NS, NY,  
ON, QC, RI.  It is distributed throughout North America except for  
the southeast.

The common species in Nova Scotia are Meloe angusticollis and Meloe  
impressus. They are interesting beetles in several regards. Adults  
are phytophagous and feed on leaves and flowers of a variety of  
plants, however, the larvae are parasitoids of ground-nesting bees in  
whose nests they live. The soft portions of the bodies of these  
beetles contain a vesicating substance called cantharidin (produced  
by the male and transferred to the female during copulation). Adults  
can secrete this orange-coloured liquid from the joints of the legs,  
which is highly caustic and can cause blisters (in fact, in rare  
instances, it has caused the death of horses who consumed beetles on  
foliage).

I have a particular fondness for these beetles since in Czech they  
are called "Majka filakova" (the violet Majka) and hence are my  
family's namesake! :-> "Majka" in this case derives from the month of  
May (= Maj) when they often appear in the Carapathians. Hence "Majka"  
means a "May beetle" in the same sense that we have "June bugs" here  
in North America.

Cheers!

Chris
