Bugs - You Should NOT Touch!

1) Family Meloidae - Blister Beetles 

Blister beetle welts and blisters can be painful, but the skin reaction isn’t life-threatening to humans, and it doesn’t typically cause permanent damage to the skin.

However, while these blisters aren’t dangerous to your skin, it’s important to use care to avoid spreading cantharidin to your eyes. This can happen if you touch a blister or welt and then rub your eyes. You may develop a type of conjunctivitis called Nairobi eye.

Washing your eye with soap and water may ease irritation from Nairobi eye, but you should also see an eye doctor for treatment.

Found these at a nature park at the end of the morning walk, they were 100's.Lucky was able to snap a couple shots with no contact.

3) Passion vine

In San Antonio area:

  • Fringed Passionflower (Passiflora ciliata) Invasive non-native species
    Usually larger, darker, more well-defined leaves with the lobes usually being more angular and coming to a point
    Stems and leaves can be anywhere between hairless to densely hairy
    Leaves have little to no smell when lightly rubbed
    Usually white or pink coronal filaments with pinkish petals/sepals
    Hairless fruit that turns red at full maturity
    An introduced species, usually found on disturbed sites / around human habitation
    Aggressive growth habit; spreading
    Invasive non-native species
  • Stinking Passionflower (Passiflora foetida)
    Usually smaller lighter green leaves with the same basic shape as the leaves of P. ciliata, although with more rounded lobes, usually not coming to a defined point
    Leaves densely hairy; truly velvet-like in texture
    Leaves give off a strong funky smell when lightly rubbed (to me it smells like cheese)
    Usually purple/bluish coronal filaments with white petals/sepals
    Hairy fruit that stays green at full maturity
    Native species usually found on less disturbed sites, mainly found on the south Texas coastal plains
    Smaller, less vigorous species than P. ciliata; not spreading
    Reaches the northern limit of its range in Texas around San Antonio
    Much, much less common in Bexar county than the introduced P. ciliata

The vast majority of "P. foetida" observations in our area on iNaturalist at the moment are misidentified P. ciliata.

Here is a good example of the real P. foetida:
