This is probably one of the least offensive of the electro fairies as it is not innately destructive, being more inclined towards hoarding and thievery than vandalism.
The nesting impulse in these fairies is quite impressive, driving them to collect shiny items to use in construction of a mating display. This breed is very easily confused when presented with multiple choices. Which inspired the folk protection of placing a coin in each corner of an infested room (it drastically reduces the thefts).
Although down the back of the sofa is usually the most common nesting site, they can be found under beds and in unused handbags or jackets. The Penny Pincher shows very little fear of humans and even after a nest is disturbed the penny pincher will return to rebuild. Only regular disruption or capture will eliminate the infestation. I have heard unconfirmed reports of aquatic cousins of this breed nesting in wishing wells and fountains. If anyone has any evidence of these I’d be very interested in reviewing it.
It is usually easier to identify these fairies when the nest is located rather than by the individual appearance. Certainly, if offered a coin, it’s rare that they can resist the temptation to steal it away. Much akin to ants, the coiled body structure makes them capable of lifting items several times their own weight.
