(TRICHODES, Herbst.) 
This genus contains a considerable number of species, which are 
widely distributed, but which appear to be more characteristic of 
temperate climates than the other members of the family ; no less than 
seventeen species are found in Europe, a number exceeding all the 
other European members of the Clerina and Tillina taken together ; 
the genus is widely distributed in North America, and is represented 
in Siberia; the species are in most cases very handsome, brightly 
coloured and conspicuous insects, and may be known by their strong, 
compact and abrupt club, and by the formation of the palpi; some of 
them appear to be very variable. 
The perfect insects are usually found on flowers, but the larve are 
exceedingly destructive to bees and wasps of various species; that of 
T. alvearius is described and figured by Westwood (Classification, 
i. p. 262, fig. 29, 9); these larve appear to be rather broader and 
plumper than those belonging to some of the other Cleride, and rather 
broader in front ; otherwise they do not differ materially from them ; 
they are of a beautiful red colour, and are spoken of by Swammerdam, 
who first described their habits, as “red worms;” the females manage 
to lay their eggs in the bees’ cells, and the larva first devours the grub 
in the cell in which it is hatched, and then proceeds from cell to cell 
devouring the inhabitant of each until it comes to maturity ; it then 
forms a small cocoon in which it changes to a pupa, and when it 
emerges as a perfect insect it is enabled to escape, as it is too hard to 
be affected by the stings of the bees.
